Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a cable specifically designed for radar monitoring and its usage method. Background Technology

[0002] In the radar field, power cables are commonly used to transmit electrical energy, and control cables are used to transmit signals. For example, Chinese application number CN201921996807.X discloses a cable for mobile radar monitoring, which includes multiple power cable cores and control cable cores. The control cable cores include multiple control wire cores and tensile ropes. The outer surface of the tensile rope is extruded with a first tensile layer. The surface of the first tensile layer is provided with multiple first receiving grooves. The multiple control wire cores correspond one-to-one with the multiple first receiving grooves. The multiple control wire cores are wrapped with a first high-strength fiber braided layer. The outer surface of the first high-strength fiber braided layer is provided with a second control wire core shielding layer and a second tensile layer. The outer surface of the second tensile layer is provided with multiple second receiving grooves. The multiple power cable cores correspond one-to-one with the multiple second receiving grooves. The multiple power cable cores are wrapped with a second high-strength fiber braided layer. The outer surface of the second high-strength fiber braided layer is provided with an inner sheath, a reinforcing layer, an outer sheath layer, and an anti-aging layer from the inside out. However, because radar monitoring requires frequent location changes, the aforementioned cables inevitably come into contact with the ground during use. When the radar moves, the cables drag on the ground, and to accommodate radar movement, the cables are generally quite long, causing excess cable to accumulate and coil near the radar, thus affecting personnel. To solve these problems, some systems incorporate cable installation structures to overhead the cables, avoiding ground contact and tangling. However, most existing cable installation structures are fixed to the equipment, which cannot effectively accommodate cable movement and adjustment. Furthermore, the installation position of the cables remains unchanged, failing to adapt to the changing environment. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a cable specifically designed for radar monitoring and its usage method.

[0004] The technical problem to be solved by this invention is achieved by the following technical solution:

[0005] A cable specifically designed for radar monitoring includes a cable core, a shielding layer, an anti-interference layer, a flame-retardant layer, an inner liner layer, and an abrasion-resistant sheath layer sequentially wrapped around the cable core. The outer wall of the abrasion-resistant sheath layer has a protruding positioning block. A sleeve block is fitted over the abrasion-resistant sheath layer. Inside the sleeve block is a fixing engagement assembly that engages with the protruding positioning block to secure the sleeve block. An external fixing assembly is provided on the outer surface of the sleeve block.

[0006] Preferably, the protruding positioning block has an arc-shaped structure, and several protruding positioning blocks are equidistantly distributed along the circumferential direction on the same cross section of the wear-resistant sheath layer. Several protruding positioning blocks on the same cross section form a group, and several groups are equidistantly distributed along the axial direction of the wear-resistant sheath layer.

[0007] Preferably, the fixing engagement assembly includes an inner groove formed on the inner annular surface of the sleeve block and radially distributed along the cable, an engagement block slidably mounted in the inner groove, a first spring connected to the groove wall of the inner groove and the engagement block, a rotating shaft axially distributed in the inner groove and axially movable, and a pressing cam disposed on the rotating shaft and abutting against the back of the engagement block. One end of the rotating shaft extends out of the end face of the sleeve block and a rotating block is disposed on that end.

[0008] Preferably, the interlocking block includes a block plate that is connected to the first spring and abuts against the pressing cam, and a plurality of interlocking clips that are equidistantly distributed on the block plate along the cable axis, wherein the interlocking clips have an arc-shaped structure.

[0009] Preferably, the rotating shaft has symmetrically arranged convex edges distributed in the same direction, and the pressing cam has convex edge grooves that cooperate with the convex edges.

[0010] Preferably, a mating hole is provided on the wall of the built-in groove corresponding to the end of the rotating shaft, and a second spring connected to the end of the rotating shaft is provided at the bottom of the mating hole.

[0011] Preferably, the mating hole includes a first stepped hole whose inner contour matches the outer contour of the convex edge, and a second stepped hole whose inner contour matches the outer contour of the rotating shaft.

[0012] Preferably, the fixed external assembly includes a mounting base disposed on the outer surface of the sleeve block, an external plate screwed into the mounting base, and a suction cup disposed at the middle position of the external plate.

[0013] Preferably, the outer plate is provided with a rotatable annular block, and the annular block is evenly distributed with a plurality of mounting threaded holes, and the annular block and the suction cup are concentrically distributed.

[0014] A method for using a cable specifically designed for radar monitoring, comprising the following steps:

[0015] Step (1) First, adjust the sleeve block to a movable state: Pull the rotating shaft outward by rotating the block to make the end of the rotating shaft exit from the mating hole. Then, rotate the rotating shaft by rotating the block to make the near end wheel surface of the pressing cam abut against the fitting block. Under the action of the first spring, the fitting block disengages from the protruding positioning block and resets to the inner groove. Then, release the rotating block, and the rotating shaft is pushed into the mating hole under the action of the second spring.

[0016] After adjusting the sleeve block to a movable state in step (2), the sleeve block can be pushed to move along the cable axis or rotate around the cable circumference. After moving or rotating the sleeve block to a suitable position according to the usage requirements, the sleeve block is adjusted to a fixed locking state: pull the rotating shaft outward again by rotating the block so that the end of the rotating shaft exits from the mating hole. Then rotate the rotating shaft by rotating the block so that the far end wheel surface of the pressing cam abuts against the locking block. Under the action of the pressing cam, the locking block extends out from the built-in groove and inserts into the convex positioning blocks distributed along the cable axis to engage with each other. Then release the rotating block, and the rotating shaft is pushed back into the mating hole under the action of the second spring.

[0017] Step (3) After the sleeve block has been moved or rotated to the appropriate position, select suction cup adsorption connection or bolt connection according to the structure of the surface to be fixed;

[0018] When selecting the bolt connection method in step (four), if the threaded hole on the fixing surface does not correspond to the mounting threaded hole on the outer plate, the ring block can be rotated for adjustment.

[0019] The beneficial effects of this invention are:

[0020] Compared with existing technologies, this invention features rapid installation, wide applicability, and strong usability. Through a protruding positioning block on the outer surface of the cable, a sleeve block fitted around the cable with a fixed external component, and a fixed engaging component inside the sleeve block that can be adapted to and fitted with the protruding positioning block, the sleeve block can be adjusted to adapt to the usage environment, and the fixed external component enables rapid installation. Furthermore, the suction cup and annular block with threaded holes allow for both suction cup adsorption and bolt connection methods, enabling the selection of the appropriate connection method based on the type of external structure.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1 to 6 As shown, a cable specifically designed for radar monitoring includes a cable core 1, a shielding layer 2, an anti-interference layer 3, a flame-retardant layer 4, an inner liner layer 5, and an abrasion-resistant sheath layer 6 sequentially covering the outside of the cable core 1. The outer wall of the abrasion-resistant sheath layer 6 is provided with an outwardly protruding positioning block 7. A sleeve block 8 is fitted onto the outside of the abrasion-resistant sheath layer 6. The inside of the sleeve block 8 is provided with a fixing engagement assembly that engages with the outwardly protruding positioning block 7 to fix the sleeve block 8. A fixing external component is provided on the outer surface of the sleeve block 8.

[0031] The shielding layer 2, anti-interference layer 3, flame-retardant layer 4, inner lining layer 5, and wear-resistant sheath layer 6 sequentially serve to prevent signal exposure, resist signal interference, provide flame retardancy, protect against pressure, and resist wear and aging. The protruding positioning block 7 and the wear-resistant sheath layer 6 are an integral structure made of the same material. The upper, lower, and left sides of the sleeve block 8 are planar, and the fixing external assembly is disposed on the upper side of the sleeve block 8. The sleeve block 8 is fitted onto the outside of the cable and can move along the cable axis or rotate circumferentially. Through the fixing engagement assembly, the sleeve block 8 can be fixed in any position after movement or rotation, realizing the ability to adapt its installation position according to the usage environment and greatly improving its applicability.

[0032] As a further improvement of the present invention, the protruding positioning block 7 has an arc-shaped structure, and a plurality of protruding positioning blocks 7 are equidistantly distributed along the circumferential direction on the same cross section of the wear-resistant sheath layer 6. The plurality of protruding positioning blocks 7 on the same cross section form a group, and the wear-resistant sheath layer 6 has a plurality of groups equidistantly distributed along its axial direction. In this embodiment, four protruding positioning blocks 7 are provided on the same cross section of the wear-resistant sheath layer 6.

[0033] As a further improvement of the present invention, the fixed engagement assembly includes an inner groove 9 formed on the inner annular surface of the sleeve block 8 and distributed radially along the cable, an engagement block 10 slidably mounted in the inner groove 9, a first spring 11 connected to the groove wall of the inner groove 9 and the engagement block 10, a rotating shaft 12 distributed axially in the inner groove 9 and axially movable, and a pressing cam 13 disposed on the rotating shaft 12 and abutting against the back of the engagement block 10. One end of the rotating shaft 12 extends out of the end face of the sleeve block 8 and a rotating block 14 is disposed on that end.

[0034] The locking block 10 includes a locking plate 101 connected to the first spring 11 and abutting against the pressing cam 13, and a plurality of locking bodies 102 equidistantly distributed along the cable axis on the locking plate 101. The locking bodies 102 have an arc-shaped structure. In this embodiment, nine locking bodies 102 are provided.

[0035] Two sets of axially adjacent protruding positioning blocks 7 on the outer surface of the cable are circumferentially staggered, so that when engaged, the engaging locking body 102 is located between two adjacent axially adjacent protruding positioning blocks 7 and two adjacent circumferentially adjacent protruding positioning blocks 7, thereby limiting and fixing the sleeve block 8 in the axial and circumferential directions. Four first springs 11 are provided, correspondingly distributed around the back of the locking plate 101.

[0036] The rotating shaft 12 is symmetrically provided with convex edges 121 distributed in the same direction, and the pressing cam 13 is provided with convex edge grooves 131 that cooperate with the convex edges 121.

[0037] A mating hole 15 is provided on the rear side wall of the built-in groove 9 corresponding to the end of the rotating shaft 12. A second spring 16 connected to the end of the rotating shaft 12 is provided at the bottom of the mating hole 15. Under the action of the second spring 16, the end of the rotating shaft 12 and the end of the protrusion 121 are located in the mating hole 15.

[0038] The protruding edge 121, besides cooperating with the protruding edge groove 131 to drive the pressing cam 13 to rotate synchronously and in the same direction, also cooperates with the mating hole 15 to limit the rotation of the rotating shaft 12. The rotating block 14, in addition to driving the rotating shaft 12 to rotate, can also pull the rotating shaft 12 outwards, causing the end of the rotating shaft 12 and the protruding edge 121 to retract from the mating hole 15.

[0039] Furthermore, the mating hole 15 includes a first stepped hole 151 whose inner contour matches the outer contour of the protruding edge 121, and a second stepped hole 152 whose inner contour matches the outer contour of the rotating shaft 12. The first stepped hole 151 serves to limit the rotation of the rotating shaft 12, and the second stepped hole 152 serves to guide the axial movement of the rotating shaft 12.

[0040] As a further improvement of the present invention, the fixed external assembly includes a mounting base 17 disposed on the outer surface of the sleeve block 8 and an external plate 18 screwed into the mounting base 17. A suction cup 19 is disposed at the middle position of the external plate 18. A rotatable annular block 20 is disposed on the external plate 18, and a plurality of mounting threaded holes 201 are evenly distributed on the annular block 20. The annular block 20 and the suction cup 19 are concentrically distributed. In this embodiment, six mounting threaded holes 201 are provided. The external plate 18 is threaded onto the mounting base 17, allowing adjustment of the external connection distance. The design of the suction cup 19 and the mounting threaded holes 201 allows the present invention to have both suction cup adsorption connection and bolt connection methods, greatly improving the applicability of the present invention.

[0041] Working principle and usage process of this invention:

[0042] In use, first adjust the sleeve block 8 to a movable state: pull the rotating shaft 12 outward by rotating block 14, so that the end of the rotating shaft 12 exits from the mating hole 15. Then rotate the rotating shaft 12 by rotating block 14, so that the proximal wheel surface of the pressing cam 13 abuts against the engaging block 10. Under the action of the first spring 11, the engaging block 10 disengages from the protruding positioning block 7 and resets into the inner groove 9. Then release the rotating block 14, and the rotating shaft 12 is pushed into the mating hole 15 under the action of the second spring 16. After the sleeve block 8 is adjusted to a movable state, it can be pushed to move along the cable axis or rotate around the cable circumference. After moving or rotating the sleeve block 8 to a suitable position according to the usage requirements, adjust the sleeve block 8 to a fixed engaging state: pull outward by rotating block 14 again. The rotating shaft 12 is moved so that its end retracts from the mating hole 15. Then, the rotating shaft 12 is rotated by the rotating block 14 so that the far end of the pressing cam 13 abuts against the fitting block 10. Under the action of the pressing cam 13, the fitting block 10 extends from the built-in groove 9 and inserts between the axially distributed protruding positioning blocks 7 of the cable to fit together. Then, the rotating block 14 is released, and the rotating shaft 12 is pushed back into the mating hole 15 under the action of the second spring 16. After the sleeve block 8 moves or rotates to the appropriate position, the suction cup 19 is selected for adsorption connection or bolt connection according to the structure of the surface to be fixed. When the bolt connection method is selected, if the threaded hole on the surface to be fixed does not correspond to the mounting threaded hole 201 on the outer plate 18, the annular block 20 can be rotated for adjustment.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention.
