They play multiple roles such as controlling installation, connecting equipment, and transmitting power and signals. It can be said that cables are the most basic components of engineering monitoring. However, the environment at the mining site is very harsh and chaotic. Cables are prone to failure due to long-term overload operation, high temperatures, mechanical shock, moisture in the insulation layer, and chemical corrosion.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the structure of a cable protection device provided in an embodiment of the present application; Figure 2 A schematic diagram of the partial structure of the buffer mechanism of the cable protection device provided in an embodiment of the present application; Figure 3 A cross-sectional view of a cable protection device provided in an embodiment of the present application; Figure 4 for Figure 2 A partial enlarged view of the middle A; Figure 5 for Figure 3 A partial enlarged view of point B in the middle.

[0037] Please refer to Figures 1 to 3 The present application provides a cable protection device, including a heat dissipation mechanism 1, a moisture-proof mechanism 2, a buffer mechanism 3 and a positioning mechanism 4; in the cable protection device, the heat dissipation mechanism 1, the moisture-proof mechanism 2 and the buffer mechanism 3 are sequentially sleeved on the cable from the inside to the outside, the heat dissipation mechanism 1 can dissipate heat for the cable, the moisture-proof mechanism 2 can prevent moisture from the cable, and the buffer mechanism 3 can provide buffering protection for the cable; in the cable protection device, the positioning mechanism 4 can be connected to the cable, and can also be connected to any one of the heat dissipation mechanism 1, the moisture-proof mechanism 2 and the buffer mechanism 3, for suspending the cable.

[0038] In this embodiment, the heat dissipation mechanism 1, the moisture-proof mechanism 2 and the buffer mechanism 3 surround the cable from the inside to the outside in sequence. It can be seen that the heat dissipation mechanism 1, the moisture-proof mechanism 2 and the buffer mechanism 3 all have annular characteristics. For example, any one of the heat dissipation mechanism 1, the moisture-proof mechanism 2 and the buffer mechanism 3 is annular or annularly distributed. In this embodiment, the heat dissipation mechanism 1 is in contact with the cable, and it has good thermal conductivity, and can quickly transfer the heat of the cable to the circumferential outer side of the cable, which is used to dissipate heat from the cable; the buffer mechanism 3 is arranged on the outer layer of the cable protection device, and it has a buffering characteristic. For example, the buffer mechanism 3 includes an elastic damping member, which can absorb the impact of external force on the cable, and is used to provide buffering protection for the cable; the moisture-proof mechanism 2 is arranged between the heat dissipation mechanism 1 and the buffer mechanism 3, and it has water absorption characteristics and / or waterproof characteristics, which can prevent water from contacting the cable, and is used to prevent moisture from the cable.

[0039] In this embodiment, the positioning mechanism 4 can support the cable upward, for example, the positioning mechanism 4 lifts the cable upward through a column so that the cable is installed overhead at the construction site; the positioning mechanism 4 can also hoist the cable, for example, the positioning mechanism 4 hoists the cable through a rigid connector so that the cable is suspended in the air at the construction site.

[0040] From the above, it can be seen that the cable protection device provided by the present application is arranged around the cable, and can provide heat dissipation, moisture-proofing, buffering and other protections for the cable, and the multiple protection layers are distributed, which is not only adapted to the operating characteristics of the cable, but also allows different protections to assist each other and better protect the cable. In addition to the multiple protections such as heat dissipation, moisture-proofing and buffering provided by the heat dissipation mechanism 1, the moisture-proof mechanism 2, and the buffer mechanism 3, the cable protection device provided by the present application also uses a positioning mechanism 4 to install the cable in the air, so that the cable is away from the harsh ground environment, and the positioning mechanism 4 can also reduce the probability of external force being transmitted to the cable.

[0041] The cable protection device provided in the present application is further described below in conjunction with the accompanying drawings and implementation examples.

[0042] For reference Figure 3 In some embodiments, the cable protection device provided by the present application further includes a first rigid tube 5 and a second rigid tube 6; the first rigid tube 5 and the second rigid tube 6 are mutually sleeved and both sleeve the cable. Generally, the first rigid tube 5 can be arranged between the buffer mechanism 3 and the moisture-proof mechanism 2, and can serve as the installation basis of the buffer mechanism 3 and the moisture-proof mechanism 2, and can also play a certain impact-proof and waterproof role. The second rigid tube 6 is arranged in the first rigid tube 5 and also in the moisture-proof mechanism 2. The heat dissipation mechanism 1 is arranged in the second rigid tube 6, that is, the second rigid tube 6 can serve as the installation basis of the heat dissipation mechanism 1.

[0043] In the above embodiment, the first rigid tube 5 and the second rigid tube 6 are inserted between the heat dissipation mechanism 1, the moisture-proof mechanism 2 and the buffer mechanism 3, and can serve as the rigid skeleton of the cable protection device to ensure the positioning and installation of each mechanism, and can also assist each mechanism to achieve better heat dissipation, moisture-proof and buffering effects on the cable.

[0044] For reference Figures 1 to 3In some embodiments, the buffer mechanism 3 may include an elastic member and a buffer plate 31; a buffer mechanism 3 includes a plurality of buffer plates 31, all of which are surrounded by the elastic member to form a cylindrical protective shell, and the protective shell is sleeved with the elastic member to surround the elastic member. When an external force impacts a buffer plate 31, the buffer plate 31 moves into the protective shell, and at the same time, the part of the elastic member corresponding to the buffer plate 31 is compressed and deformed. It can be seen that when the cable protection device is used to surround the cable, if an external force impacts the cable, the buffer structure of the cable protection device can first respond to the impact, specifically, the external force will cause a partial depression of the protective shell, and the protective shell and the elastic member can absorb the impact energy of the external force.

[0045] All the buffer plates 31 of the above-mentioned buffer mechanism 3 are spliced ​​on the surrounding side of the elastic member to form a cylindrical protective shell. No matter which direction the external force comes from, it will first hit the buffer plate 31 and compress the elastic member, thereby buffering the impact force, reducing its strength, protecting the cable, greatly reducing the impact on the cable when hit by external force, and effectively preventing the cable from mechanical damage.

[0046] The elastic member of the above-mentioned buffer mechanism 3 can be set as a plurality of relatively independent, retractable elastic damping structures, or an elastic sleeve member can be set. In the various embodiments provided in the present application, the elastic member is preferably set as a plurality of relatively independent elastic damping structures, and these elastic damping structures can correspond to all buffer plates 31 one by one. When an external force impacts a certain buffer plate 31, the elastic damping structure corresponding to the buffer plate 31 is compressed and deformed, and the remaining elastic damping structures are not affected. For example, the elastic member may include a plurality of retractable buffer springs 32; all buffer springs 32 are distributed in a ring, all buffer plates 31 and all buffer springs 32 are connected one by one, and any buffer spring 32 is retracted and contracted along the radial direction of the cable.

[0047] Still available for reference Figures 1 to 3 On the basis of the above embodiment, the buffer mechanism 3 may further include a fixing ring 33. Figure 1 In the embodiment, the fixing ring 33 is hooped around the outer circumference of all buffer plates 31 , so that all buffer springs 32 can be in a compressed state with a preset compression amount. Of course, the preset compression amount of all buffer springs 32 is less than the maximum compression amount of the buffer springs 32 .

[0048] The fixing ring 33 may specifically include a left fixing ring 33, a right fixing ring 33 and a fastening bolt; one of the left fixing ring 33 and the right fixing ring 33 is installed on the positioning mechanism 4 and the other is hinged to the positioning mechanism 4. When the fixing ring 33 and the buffer plate 31 of the buffer mechanism 3 are installed, the left fixing ring 33 and the right fixing ring 33 are both close to the outer surface of the entire buffer plate 31, and the fastening bolt is passed through and locked between the left fixing ring 33 and the right fixing ring 33.

[0049] For reference Figure 1 In some embodiments, the positioning mechanism 4 includes a retractable support platform 41; the support platform 41 is connected to the fixing ring 33, for example, the support platform 41 is arranged below the fixing ring 33, and the top of the support platform 41 is fixedly connected to the fixing ring 33, and can lift the fixing ring 33 upward, thereby lifting the positioning cable protection device and the cable it protects, so that the cable is away from the ground that is more likely to cause a fault, thereby reducing the possibility of cable failure at the source. The aforementioned support platform 41 has a retractable characteristic, for example, the support platform 41 may include a hollow outer rod 411 and an inner support rod 412, the inner support rod 412 is inserted into the hollow outer rod 411, and the inner support rod 412 and the hollow outer rod 411 are slidably connected, and the operator can adjust the telescopic size of the inner support rod 412 and the hollow outer rod 411 according to the construction requirements of the cable.

[0050] In the above embodiment, the positioning mechanism 4 further includes a hand-tightening bolt 42, which passes through the hollow outer rod 411 and presses against the inner support rod 412, thereby locking the hollow outer rod 411 and the inner support rod 412; the hollow outer rod 411 and the inner support rod 412 can be connected by a threaded rod.

[0051] like Figure 1 As shown, a pointed cone 43 may be provided at the bottom end of the hollow outer rod 411 to facilitate the secure insertion and fixing of the hollow outer rod 411 in the construction site, thereby improving the installation strength of the support platform 41 .

[0052] For reference Figure 3 and Figure 4 In some embodiments, the heat dissipation mechanism 1 may include a heat pipe 11 and a plurality of heat sinks 12 disposed in the heat pipe 11; any heat sink 12 includes a first end for pressing against the cable and a second end connected to the heat pipe 11, and the first ends of all heat sinks 12 are distributed in a circle and face the cable, and may surround the outer circumference of the cable. In this embodiment, the cable is positioned by squeezing the first end of the heat sink 12, and the first ends of all heat sinks 12 disperse and surround the cable, which can position the cable and reduce the friction between the cable and the cable protection device.

[0053] In the above embodiment, the heat sink 12 can be specifically set as a copper sheet, and the heat pipe 11 can be specifically set as an aluminum tube. One end of all the copper sheets can be inserted and fixed in the second rigid tube 6; the other end of all the copper sheets is exposed in the tube cavity of the second rigid tube 6 to press the cable. Copper has very good instantaneous heat absorption ability and high specific heat capacity, which can absorb more heat and heat up slowly. The heat dissipation speed of aluminum is faster than that of copper. Therefore, the copper sheet can quickly absorb the heat emitted by the cable and transfer the heat to the aluminum tube, which then continuously dissipates the heat, thereby controlling the temperature of the cable and preventing the cable from being too hot and accelerating aging or failure.

[0054] like Figure 2 and Figure 4As shown, in the above embodiment, a first end of any heat sink 12 is provided with a guiding curved surface 121; the guiding curved surface 121 of any heat sink 12 faces the cable, and the guiding curved surfaces 121 of all heat sinks 12 converge toward the central axis of the second rigid tube 6; in addition, any one of the guiding curved surfaces 121 bends and extends toward both ends of the heat conducting pipe 11, and at the same time, any one of the guiding curved surfaces 121 bends and extends toward the inner wall on the same side of the heat conducting pipe. For example, the guiding curved surface 121 may be in the shape of an arch, which may guide the cable to be installed in the cable protection device.

[0055] For reference Figure 3 and Figure 5 In some embodiments, the moisture-proof mechanism 2 may include a third rigid tube 21, a flexible sleeve 22 and a water-absorbing filling layer 23; wherein the flexible sleeve 22 is arranged on the outer periphery of the third rigid tube 21, and the water-absorbing filling layer 23 is filled between the third rigid tube 21 and the flexible sleeve 22. The moisture-proof mechanism 2 is arranged between the heat dissipation mechanism 1 and the buffer mechanism 3, and the water-absorbing filling layer 23 can absorb the water vapor condensed between the heat dissipation mechanism 1 and the buffer mechanism 3.

[0056] In the above embodiment, the third rigid tube 21 can be specifically configured as a container tube, the flexible sleeve 22 can be specifically configured as a non-woven fabric layer, and the water-absorbing filling layer 23 can be specifically configured as activated carbon. The container tube can be installed on the aluminum tube of the heat dissipation mechanism 1; baffles are installed at both ends of the container tube, and the non-woven fabric layer is installed on the baffles at both ends of the container tube; the activated carbon is filled between the non-woven fabric layer and the container tube.

[0057] The cable protection device sets the heat dissipation mechanism 1 on the second rigid tube 6, and the outer periphery of the second rigid tube 6 can be provided with a corrosion-resistant coating; the cable protection device sets the first rigid tube 5 between the buffer mechanism 3 and the moisture-proof mechanism 2, and a waterproof coating can be provided between the first rigid tube 5 and the flexible sleeve 22. The corrosion-resistant coating can be specifically set as a polytetrafluoroethylene coating 7, which has high corrosion resistance and stable physical properties, can protect the cable protection device and the cables inside it from chemical corrosion, and effectively protect the cables. The waterproof coating can be specifically set as a polyurethane coating 8, which is brushed on the outer surface of the flexible sleeve 22, such as a non-woven fabric layer, and at the same time, the polyurethane coating 8 also abuts against the inner wall of the first rigid tube 5.

[0058] In the above embodiment, the polyurethane coating 8 can block most of the water vapor, and part of the water vapor that passes through the polyurethane coating 8 and the non-woven fabric layer can be completely adsorbed by the activated carbon, thereby effectively resisting the intrusion of water vapor, preventing the cable from being damp for a long time and damaging its insulation strength, and protecting the cable from failure.

[0059] In summary, the cable protection device provided in the present application includes a buffer mechanism 3, a first rigid tube 5, a moisture-proof mechanism 2, a second rigid tube 6, and a heat dissipation mechanism 1, which are distributed in sequence from the outside to the inside, and also includes a positioning mechanism 4 that supports the aforementioned buffer mechanism 3; the first rigid tube 5 and the second rigid tube 6 are coaxially distributed, the heat dissipation mechanism 1 is arranged on the second rigid tube 6, the moisture-proof mechanism 2 is installed on the outside of the heat dissipation mechanism 1, the moisture-proof mechanism 2 is abutted against the inner wall of the first rigid tube 5, a plurality of buffer plates 31 of the buffer mechanism 3 are installed at equal intervals on the outside of the first rigid tube 5, and a plurality of support platforms 41 are installed on the first rigid tube 5.

[0060] The cable protection device provided in the present application quickly absorbs the heat of the cable through the heat dissipation mechanism 1, thereby controlling the temperature of the cable and effectively preventing the cable from malfunctioning due to overtemperature; the cable protection device isolates the intrusion of water or water vapor through the moisture-proof mechanism 2, prevents the humid environment from damaging the insulation strength of the cable, and reduces the probability of cable failure; the cable protection device reduces the impact of external force on the cable through the buffer mechanism 3, avoiding mechanical damage to the cable; the cable protection device firmly supports the cable through the positioning mechanism 4, so that the cable is off the ground, and the cable can be kept away from places with high failure rates.
