Description

Technical Field

[0001] The present invention relates to the technical field of power cables, and in particular to a highly flame-retardant and highly wear-resistant power cable. Background Art

[0002] Some large industrial equipment requires a large amount of electricity, so cables need to be connected for power transmission. When these large equipment are working and moving, the cables will move driven by the equipment, and the cables will be dragged back and forth. At the same time, due to the high current passing through the cables, the temperature of the cables is also high, so the cables used on large equipment need to have high flame retardancy and high wear resistance to prevent the cables from being damaged by more friction when dragging. At the same time, the cables are close to large equipment. If they are too close to high temperature areas, the cable surface will melt or burn, which will cause the fire to spread.

[0003] Traditionally, cables used on large equipment use drag chain cables. Drag chains are installed on the cables to protect them. However, the drag chain can only reduce the friction of the cables by wrapping them, which will also affect the rotation angle of the cables themselves and reduce the possibility of the cables coming into contact with fire sources. However, when the cables spontaneously combust due to short circuits or insulation damage, it cannot help the cables to be flame retardant. Therefore, in order to prevent the occurrence and expansion of combustion without affecting the rotation and bending of the cables themselves, the cables must be protected from fire. Summary of the invention

[0004] The present invention provides a highly flame-retardant and highly wear-resistant power cable, which solves the problem in the prior art that the power cable used on traditional equipment is difficult to effectively prevent burning while ensuring the rotation and bending angle.

[0008] The supporting and fixing component includes an extrusion seat and a sliding seat. There are two extrusion seats, which are arranged opposite to each other. The tightening belt passes through the extrusion seat and is slidably connected. The sliding seat is arranged between the two sliding seats and is rotatably connected to the two extrusion seats.

[0009] The fire extinguishing assembly includes a fireproof frame and a gas cylinder. The fireproof frame is slidably connected to two relatively arranged sliding seats on the two elastic fixing assemblies. An opening is provided on the fireproof frame, and the opening is arranged toward the cable. The gas cylinder is detachably arranged in the fireproof frame.

[0010] The protection mechanism includes a protection frame 1, a protection frame 2 and a protection plate. The protection frame 1 is arranged in an arc shape, the protection frame 2 is arranged in an arc shape, the protection frame 1 is rotatably connected to the protection frame 2, the protection frame 1 and the protection frame 2 are detachably arranged on a cable, the protection frame 1 and the protection frame 2 are both provided with the protection plate, and a plurality of support wheels are provided on the protection plate, wherein the steering connection mechanism is detachably connected to the protection frame 1 and the protection frame 2.

[0011] When the protection frame 1 and the protection frame 2 are rotated and fitted together, the protection frame 1 and the protection frame 2 are fixed by pins. At this time, the protection frame 1 and the protection frame 2 are sleeved on the cable.

[0012] When the protective frame 1 and the protective frame 2 are in contact with each other, a circular track 1 and a circular track 2 are formed on both sides. The circular track 1 is arranged on the side close to the cable, and the circular track 2 is arranged on the side away from the cable.

[0014] The working principle and beneficial effects of the present invention are:

[0015] 1. In the present invention, by providing an extrusion seat and a sliding seat, after the extrusion seat is attached to the cable, the cable bends so that the two extrusion seats slidably connected to the same fireproof frame cannot maintain axial alignment.

[0016] 2. In the present invention, a fireproof frame and a gas cylinder are provided, the opening of the fireproof frame faces the cable, and the gas cylinder is filled with high-pressure carbon dioxide and dry powder in a dry powder fire extinguisher. When the cable burns or there is a fire source on the surface of the cable, the flame heats the surface of the gas cylinder, the gas cylinder will rupture, and the gas cylinder will explode. The high-pressure carbon dioxide therein will drive the dry powder to spray around, and under the drive of the fireproof frame, it will spray in the direction of the cable. The carbon dioxide contacts the dry powder and the fire source to extinguish the fire, thereby achieving a flame retardant effect;

[0017] 3. In the present invention, by setting the adapter ring 1 and the adapter ring 2, the docking ring and the adapter ring 1 rotate on one side of the protective mechanism, and the docking ring and the adapter ring 2 rotate on the other side of the protective mechanism.

[0018] 4. In the present invention, by providing a flame retardant mechanism, carbon dioxide and dry powder can react quickly and accurately retard the cable when it burns. By providing a protective mechanism, the cable can be protected from friction with the ground by the support wheel surrounding the cable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 to Figure 6 As shown, this embodiment proposes a highly flame-retardant and highly wear-resistant power cable, including a flame-retardant mechanism, a protective mechanism and a steering connection mechanism. A plurality of flame-retardant mechanisms are provided, and the plurality of flame-retardant mechanisms can be detachably mounted on the cable, and the flame-retardant mechanism is used to perform flame retardancy when the cable burns. A plurality of protective mechanisms are provided, and the plurality of protective mechanisms can be detachably mounted on the cable, and a protective mechanism is mounted on the outside of each flame-retardant mechanism, and the protective mechanism is used to protect the outside of the cable. The steering connection mechanism is arranged on the protective mechanism, and two adjacent protective mechanisms are connected via the steering connection mechanism, wherein the flame-retardant mechanism includes an elastic fixing component, and two elastic fixing components are provided, and the two elastic fixing components are detachably mounted on the cable, and a plurality of fire extinguishing components are slidably connected to the two elastic fixing components, and the elastic fixing component is used to elastically set the fire extinguishing component near the cable, wherein the fire extinguishing component is used to extinguish the cable when the cable burns.

[0029] like Figure 1~Figure 3 As shown, the elastic fixing component includes a supporting and fixing component and a tightening belt 1. There are multiple supporting and fixing components, and the multiple supporting and fixing components are used to clamp and fix the cable. At the same time, the supporting and fixing components are slidably connected to the fire extinguishing component. The tightening belt 1 runs through the multiple supporting and fixing components. The supporting and fixing components are slidably set on the tightening belt 1, and the tightening belt 1 is sleeved on the cable. The tightening belt 1 is a structure similar to a cable tie, and both ends are detachably connected and can be locked. The multiple supporting and fixing components are tightened on the cable through the tightening belt 1, so that the supporting and fixing components surround the cable and are squeezed on the cable.

[0030] like Figure 1~Figure 3 As shown, the supporting and fixing components include an extrusion seat 2 and a sliding seat 3. There are two extrusion seats 2, and the two extrusion seats 2 are arranged opposite to each other. The tightening belt 1 passes through the extrusion seat 2 and is slidably connected. The sliding seat 3 is arranged between the two sliding seats 3 and is rotatably connected to the two extrusion seats 2. The fire extinguishing assembly is slidably connected to the sliding seat 3. In this embodiment, there are six supporting and fixing components. When the two ends of the tightening belt 1 are not butted, the tightening belt 1 drives the six supporting and fixing components to move. When the extrusion seat 2 fits the cable, the cable bends so that the two extrusion seats 2 slidably connected to the same fireproof frame 4 cannot maintain axial alignment. At this time, the sliding seat 3 rotates on the extrusion seat 2, and the fireproof frame 4 slides on the sliding seat 3. On both sides of the bending direction of the cable, the sliding seats 3 connected at both ends of the fireproof frame 4 are respectively close to and away from each other, so that the fireproof frame 4 is always kept near the cable without affecting the bending of the cable.

[0031] like Figure 2~Figure 3 As shown, the fire extinguishing assembly includes a fireproof frame 4 and a gas cylinder 6. The fireproof frame 4 is slidably connected to two relatively arranged sliding seats 3 on two elastic fixed components. An opening 5 is opened on the fireproof frame 4, and the opening 5 is arranged toward the cable. The gas cylinder 6 is detachably arranged in the fireproof frame 4, and the opening 5 on the fireproof frame 4 faces the cable. The gas cylinder 6 is filled with high-pressure carbon dioxide and dry powder in a dry powder fire extinguisher. When the cable burns or there is a fire source on the surface of the cable, the flame heats the surface of the gas cylinder 6, and the gas cylinder 6 will rupture and explode. The high-pressure carbon dioxide therein will drive the dry powder to spray around and spray in the direction of the cable under the drive of the fireproof frame 4. The carbon dioxide contacts the dry powder and the fire source to extinguish the fire, thereby achieving a flame retardant effect. When the skin of the cable is worn and broken, the metal core in the cable may rust. The resistance of the rusted metal core increases, which may cause the burning of the cable skin. At this time, the gas cylinder 6 feels the burning flame and ruptures, which on the one hand is flame retardant for the flame, and on the other hand also plays a detection role.

[0032] like Figure 4~Figure 6As shown, the protection mechanism includes a protection frame 1 7, a protection frame 2 8 and a protection plate 9, the protection frame 1 7 is set in an arc shape, the protection frame 2 8 is set in an arc shape, the protection frame 1 7 is rotatably connected with the protection frame 2 8, the protection frame 1 7 and the protection frame 2 8 are detachably arranged on the cable, the protection frame 1 7 and the protection frame 2 8 are both provided with a protection plate 9, and a plurality of supporting wheels 10 are provided on the protection plate 9, wherein the steering connection mechanism is detachably connected with the protection frame 1 7 and the protection frame 2 8, and when the protection frame 1 7 and the protection frame 2 8 are rotated and fitted, the protection frame 1 7 and the protection plate 9 can be aligned by a pin 18. The protective frame 2 8 is fixed, at this time, the protective frame 1 7 and the protective frame 2 8 are sleeved on the cable, away from the position of one end of the protective frame 1 7 and the protective frame 2 8 being rotatably connected. When the protective frame 1 7 and the protective frame 2 8 are docked, the protective frame 1 7 and the protective frame 2 8 can be fixed by the pin 18. Two protective plates 9 are respectively arranged on the protective frame 1 7 and the protective frame 2 8. The protective plates 9 surround the flame retardant mechanism. When the cable is placed on the ground, the support wheel 10 contacts the ground. When the cable is bent and rotated to various angles, the support wheel 10 contacts the ground, so as to protect the cable and the flame retardant mechanism.

[0033] like Figure 4~Figure 6 As shown, when the protective frame 1 7 and the protective frame 2 8 are fitted together, a circular track 1 11 and a circular track 2 12 are formed on both sides. The circular track 1 11 is set on the side close to the cable, and the circular track 2 12 is set on the side away from the cable. A clamping ring 13 and a clamping ring 2 14 are rotatably set on the two circular tracks 11. The clamping ring 13 and the clamping ring 2 14 are fitted with the cable. The clamping ring 13 and the clamping ring 2 14 are both set to be semicircular. The clamping ring 13 and the clamping ring 2 14 are both provided with grooves and protrusions. When the protective frame 1 7 and the protective frame 2 8 are sleeved on the cable, the clamping ring 1 13 and the clamping ring 2 14 are connected with each other to form a circular ring to clamp the cable. At this time, the circular ring formed by the protective frame 1 7 and the protective frame 2 8 rotates on the circular ring formed by the clamping ring 13 and the clamping ring 2 14 through the annular track 1 11. When the clamping ring 13 coincides with the protective frame 1 7 or the protective frame 2 8, the clamping ring 13 only contacts with the protective frame 1 7 or the protective frame 2 8. The same is true for the clamping ring 2 14. At this time, the protective frame 1 7 or the protective frame 2 8 can be rotated to open.

[0034] like Figure 4~Figure 6As shown, the steering connection mechanism includes a docking ring 15, an adapter ring 16 and an adapter ring 2 17. Two docking rings 15 are provided. The two docking rings 15 are rotatably arranged on two annular tracks 2 12 respectively, the adapter ring 16 is rotatably arranged on one of the annular tracks 2 12, and the adapter ring 2 17 is rotatably arranged on one of the annular tracks 2 12. When the clamping ring 13 is fitted with the protective frame 1 7 or the protective frame 2 8, the docking ring 15 is fitted with the protective frame 1 7 or the protective frame 2 8, and the protective frame 1 7 is fitted with the protective frame 1 7. The two 8 can be rotatably separated, the adapter ring 16 and the adapter ring 2 17 on two adjacent protective mechanisms are meshed, the docking ring 15 and the adapter ring 1 16 rotate on one side of the protective mechanism, and the docking ring 15 and the adapter ring 2 17 rotate on the other side of the protective mechanism. The adapter ring 1 16 and the adapter ring 2 17 on the two protective mechanisms are rotatably connected, which further strengthens the protection of the cable. When the cable is bent in multiple directions, the adapter ring 1 16 and the adapter ring 2 17 can rotate on the circular track 2 12 to align them with the bending direction of the cable.

[0035] In this embodiment, the tightening belt 1 is opened and wrapped around the cable, so that multiple extrusion seats 2 are in contact with the cable, the two ends of the tightening belt 1 are connected and tightened, the tightening bag tightens the extrusion seat 2 to fit the surface of the cable, and the protective frame 1 7 and the protective frame 2 8 are wrapped on the flame retardant mechanism, so that the protrusions and grooves on the clamping ring 13 and the clamping ring 2 14 are connected to each other, the clamping ring 13 and the clamping ring 2 14 are wrapped around the cable, and the pin 18 is extended into the holes on the protective frame 1 7 and the protective frame 2 8 that are rotated and connected to each other. When the cable is bent, the rotatingly connected adapter ring 16 and the adapter ring 2 17 rotate with each other. At the same time, the adapter ring 16 and the adapter ring 2 17 rotate on the two annular tracks 2 12 respectively, so that the adapter ring 16 and the adapter ring 2 The rotation direction of ring 2 17 can be aligned with the bending direction of the cable, and the protection frame 1 7 and the protection frame 2 8 can rotate on the clamping ring 13 and the clamping ring 2 14 through the annular track 11. The support wheel 10 supports the ground, so that the support wheel 10 will support the ground when the cable is dragged on the ground. When the cable at the flame retardant mechanism is bent, the two supporting and fixing components are driven to rotate. At this time, the sliding seat 3 rotates on the extrusion seat 2, and the protection frame slides on the sliding seat 3. When the cable burns, the flame arc and the high temperature contact the gas cylinder 6, and the high temperature causes the gas cylinder 6 to rupture. The compressed gas carbon dioxide in the gas cylinder 6 is sprayed out along with dry powder. The dry powder and carbon dioxide contact the burning part on the cable to extinguish the fire and minimize the scope of the burned cable.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
