[0001] This invention relates to the field of cable construction protection, and more particularly to a cable protection device for power engineering construction. Background Technology

[0002] During power construction, cables need to be temporarily laid across different locations. To prevent the cables from being run over by passing vehicles or trampled by pedestrians, existing technologies usually use fixed protection devices to temporarily fix the cables to the ground for protection. However, the routing of temporary cables often needs to be changed frequently with the progress of construction. The existing ground fixing methods are relatively laborious to dismantle and cannot meet the needs of rapid installation and removal of temporary wiring. Summary of the Invention

Each cylinder has a sliding connection with a rod; each rod is fixedly connected to several wedge blocks I; each fixed cylinder has a sliding connection with several pins, and the number and position of the pins correspond to the wedge blocks I; each pin is fixedly connected to a wedge block II; each rod is fixedly connected to a connecting plate; each connecting plate is fixedly connected to several push blocks directly below the corresponding wedge blocks II; each rod is detachably connected to a rocker; the cover plate is fixedly connected to several support plates, and the support plates are located below the rocker; the bottom plate is detachably connected to two guard plates, and the guard plates are detachably connected to the cover plate.

[0005] As an improvement to the above solution, it also includes placement slots; the cover plate has several placement slots, and the rocker is located in the placement slots.

[0006] As an improvement to the above solution, it also includes a guide plate; the fixed cylinder has a flat part, and each fixed cylinder has a notch, and the notch is located on the arc surface of the fixed cylinder; the bottom plate is fixed with two guide plates, the cross-section of the guide plates is triangular, and the guide plates are inserted into the circular hole I.

[0007] As an improvement to the above solution, the inner wall of the cable tray is roughened.

[0008] As an improvement to the above solution, it also includes a rectangular plate; the base plate has several rectangular slots, and the number and position of the rectangular slots correspond to the grooves; several rectangular plates are rotatably connected to the base plate, and torsion springs are provided between the rectangular plates and the base plate, and the rectangular plates are located in the corresponding rectangular slots; several springs are fixedly connected to the base plate; each pair of springs is jointly fixedly connected to a limiting plate; several limiting slots are provided on the base plate, and the limiting plates are inserted into the limiting slots to limit the rectangular plates.

[0009] As an improvement to the above solution, it also includes a protective sleeve; the base plate is detachably connected to several wear-resistant rubber protective sleeves, and the protective sleeves are detachably connected to the protective plate, and the cable body is fitted into the inner wall of the corresponding protective sleeve, and the inner wall of the protective sleeve is roughened.

[0010] As an improvement to the above scheme, the rectangular plate is made of alloy steel.

[0011] As an improvement to the above solution, it also includes telescopic blocks and clamping blocks; the base plate has several sliding grooves; each protective plate has a receiving groove; each sliding groove has a telescopic block made of a material with thermal expansion and contraction characteristics; each telescopic block has two clamping blocks that are in contact with the cable body, the clamping blocks slide in the corresponding receiving grooves and sliding grooves, and the clamping blocks are in contact with the corresponding protective plates; the protective plates are made of thermally conductive material.

[0012] As an improvement to the above solution, a shielding ring is also included; several shielding rings are fixed to the base plate, and the shielding rings are located on the inner wall of the corresponding wire trough.

[0013] As an improvement to the above solution, heat dissipation fins are provided on the upper side of the protective plate.

[0014] This invention has the following advantages: When it is necessary to move the position of the cable body according to the construction progress, the present invention only requires a person to step on the rocker arm to lift the plug rod upward, so that the plug rod drives the push block to move upward through the connecting plate. The push block presses the wedge block II upward, so that the wedge block II drives the plug to retract inward into the fixed cylinder, thereby lifting the plug rod off the ground. Stepping on all the rocker arms sequentially lifts all the plug rods in the fixed cylinder off the ground. Then, the person pulls the base plate upward, so that the base plate drives the fixed cylinder and its connected components off the ground, allowing for quick disassembly and transfer, thus improving disassembly and assembly efficiency.

[0015] After the cable body is removed and the cover plate is placed back on the base plate, the rectangular plate rotates upward under the action of the torsion spring until it abuts against the inner wall of the cable trough. The limiting plate is then ejected into the limiting groove under the elastic force of the spring, so that the limiting plate supports the rectangular plate, thereby supporting the cable trough and increasing the strength of the empty cable trough against external forces.

[0016] In high-temperature weather, the heat generated by the cable body is transferred to the thermoplastic elastomer expansion block, causing the expansion block to expand and extend. The expansion block then drives two clamping blocks to move in opposite directions within the groove, allowing the clamping blocks to release the obstruction between the cable body and the inner wall of the groove. This allows the heat generated by the cable body to be transferred to the protective plate through the gap, and finally dissipated to the outside by the heat-conducting protective plate, improving heat dissipation efficiency.

[0030] Example 1: A cable protection device for power engineering construction, such as Figures 1-11 As shown, it includes a base plate 1 and connectors 2; the base plate 1 is detachably connected to several connectors 2;

[0031] It also includes a cover plate 3, a fixing cylinder 101, a plug rod 102, a wedge block I 103, a plug 104, a wedge block II 105, a connecting plate 106, a push block 107, a rocker plate 108, a support plate 109, and a guard plate 201; the base plate 1 is bolted to the cover plate 3 via a connector 2; the cover plate 3 has a groove 33; the cover plate 3 has several round holes II 31; the base plate 1 has several round holes I 11, and the number and position of the round holes I 11 correspond to the round holes II 31; the cover plate 3 is connected to several fixing cylinders 101, and the fixing cylinders 101 are located inside the round holes I 11, and the fixing cylinders 101 pass through the corresponding round holes I 11 and round holes II 31; each fixing cylinder 101 is slidably connected to a plug rod 102; each plug rod 102... Each of the 02 components is fixedly connected to several wedge blocks I 103; each fixed cylinder 101 is slidably connected to several pins 104, and the number and position of the pins 104 correspond to the wedge blocks I 103; each pin 104 is fixedly connected to a wedge block II 105; each insert rod 102 is fixedly connected to a connecting plate 106; each connecting plate 106 is fixedly connected to several push blocks 107, and the push blocks 107 are located directly below the corresponding wedge block II 105; each insert rod 102 is detachably connected to a rocker 108; the cover plate 3 is fixedly connected to several support plates 109, and the support plates 109 are located below the rocker 108; the bottom plate 1 is detachably connected to two guard plates 201, and the guard plates 201 are detachably connected to the cover plate 3.

[0032] It also includes placement slots 32; the cover plate 3 has several placement slots 32, and the rocker plate 108 is located in the placement slots 32.

[0033] It also includes a guide plate 1010; the fixed cylinder 101 has a flat part 15, and each fixed cylinder 101 has a notch 1001, and the notch 1001 is located on the arc surface of the fixed cylinder 101; the bottom plate 1 is fixedly connected to two guide plates 1010, the cross-section of the guide plate 1010 is triangular, and the guide plate 1010 is inserted into the circular hole I11.

[0034] The inner wall of the cable trough 33 is roughened to increase the friction between the inner wall of the cable trough 33 and the cable body 4, thereby improving the fixing effect of the cable trough 33 on the cable body 4.

[0035] Initially, the pin 104 does not protrude from the fixing cylinder 101. In use, place the base plate 1 on a flat surface. First, remove the fixing cylinder 101 and its connected components from the round hole II 31. Then, disassemble the connector 2 and the protective plate 201, separating the cover plate 3 from the base plate 1. Next, use a drill to drill a corresponding hole in the ground with a diameter slightly smaller than that of the fixing cylinder 101, penetrating the round hole I 11. Then, place the cable body 4 on the base plate 1, and then install the cover plate 3 onto the base plate 1, securing the cable body 4 into the wire groove 33. Finally, reinstall the protective plate 201 back onto the base plate 1 and the cover plate 3. Subsequently, the cover plate 3 is re-fixed to the base plate 1 using connector 2. Next, the fixing cylinder 101 and its connected components are aligned with the circular hole II 31, and then the fixing cylinder 101 and its connected components are hammered vertically downwards into the circular hole II 31, allowing the fixing cylinder 101 to pass through the circular hole II 31 and the circular hole I 11 in sequence and enter the ground hole. Then, the insertion rod 102 is hammered downwards, causing the insertion rod 102 to drive the wedge block I 103 to generate a lateral compressive force on the insertion nail 104, thereby driving the insertion nail 104 into the ground for fixation, thus fixing the fixing cylinder 101 inside the ground hole. Figure 4 As shown, the base plate 1, cover plate 3, and cable body 4 are fixed to the ground by the fixing cylinder 101. The cover plate 3 protects the cable body 4 that is laid across the ground. When it is necessary to move the position of the cable body 4 according to the construction progress, the operator only needs to step on the rocker arm 108. The rocker arm 108 uses the support plate 109 as a fulcrum to lift the insert rod 102 upward. The insert rod 102 drives the push block 107 to move upward through the connecting plate 106. The push block 107 presses the wedge block II 105 upward, causing the wedge block II 105 to drive the pin 104 to retract inward into the fixing cylinder 101, thereby lifting the pin 104 off the ground. Stepping on all the rocker arms 108 sequentially lifts all the pins 104 in the fixing cylinder 101 off the ground. Figure 5 As shown, the base plate 1 is then manually pulled upwards, causing the base plate 1 to lift the fixed cylinder 101 and its connected components off the ground for quick disassembly and transfer, thus improving disassembly and assembly efficiency.

[0036] Under normal circumstances, the rocker 108 rotates and is placed into the placement slot 32 to prevent personnel from accidentally stepping on the rocker 108, which could cause the insertion rod 102 to pull the insertion pin 104 and cause it to loosen.

[0037] Considering that when the vehicle's wheels run over the base plate 1 and cover plate 3, the wheels will also exert a horizontal thrust on the cover plate 3, resulting in a lateral shear force between the fixing cylinder 101 and the pin 104 used to fix the base plate 1 and cover plate 3 and the ground. Over time, this will cause the fixing cylinder 101 and the pin 104 to loosen. To solve this problem, when installing the fixing cylinder 101, first make the flat part 15 of the fixing cylinder 101 face the guide plate 1010, and then vertically insert the fixing cylinder 101 into the round hole I 11 and the round hole II 31. After drilling into the ground, the fixed cylinder 101 is manually rotated 180 degrees so that the notch 1001 is engaged with the guide plate 1010. By setting the guide plates 1010 with triangular cross sections on both sides of the base plate 1, when the wheel presses on the guide plate 1010, the guide plate 1010 first applies downward pressure to the fixed cylinder 101 and the pin 104 through the notch 1001, which strengthens the fixing effect of the fixed cylinder 101 and the pin 104 and prevents the fixed cylinder 101 and the pin 104 from shifting and loosening when the wheel impacts the cover plate 3.

[0038] Example 2, based on Example 1, such as Figure 2 and Figures 6-9 As shown, it also includes a rectangular plate 202, a spring 203, and a limiting plate 204; the base plate 1 has three rectangular slots 12, and the number and position of the rectangular slots 12 correspond to the wire groove 33; the base plate 1 is rotatably connected to several rectangular plates 202, and a torsion spring is provided between the rectangular plates 202 and the base plate 1, and the rectangular plates 202 are located in the corresponding rectangular slots 12; the base plate 1 is fixedly connected to several springs 203; each pair of springs 203 is fixedly connected to a limiting plate 204; the base plate 1 has several limiting slots 14.

[0039] It also includes a protective sleeve 205; the base plate 1 is connected to several wear-resistant rubber protective sleeves 205 by snap-fit, and the protective sleeves 205 are detachably connected to the protective plate 201, and the cable body 4 is fitted into the inner wall of the corresponding protective sleeve 205, and the inner wall of the protective sleeve 205 is rough.

[0040] The rectangular plate 202 is made of alloy steel, which enhances its bending strength and thus extends its service life.

[0041] Considering that existing technologies typically involve arranging multiple cable bodies 4, there will be situations where multiple cable bodies 4 are arranged in this invention. Therefore, multiple cable grooves 33 are opened in the cover plate 3 to accommodate multiple cable bodies 4. However, when the cable grooves 33 do not need to be completely filled, empty cable grooves 33 will appear. The presence of empty cable grooves 33 will reduce the support strength of the cover plate 3. When a heavy-duty vehicle passes over the cover plate 3, the empty cable grooves 33 are prone to deformation. To solve this problem, when the cable body 4 is normally inserted into the cable groove 33, the cable body 4 presses down on the rectangular plate 202, so that the rectangular plate 202 is always Inside the rectangular groove 12, the torsion spring between the rectangular plate 202 and the base plate 1 is compressed. At this time, the limiting plate 204 is also held against the cable body 4, and the spring 203 is compressed. After the cable body 4 is removed and the cover plate 3 is placed back on the base plate 1, the rectangular plate 202 rotates upward under the action of the torsion spring until the rectangular plate 202 abuts against the inner wall of the wire groove 33. The limiting plate 204 is ejected into the limiting groove 14 under the elastic force of the spring 203, so that the limiting plate 204 supports the rectangular plate 202, thereby supporting the wire groove 33 and increasing the support strength of the empty wire groove 33 against external forces.

[0042] It is also considered that the cable body 4 arranged in the base plate 1 and cover plate 3 may be subjected to sudden external force during construction, such as when a person walking is tripped by the cable body 4. At this time, the cable body 4 may bend and shift at the end face of the protective plate 201. Therefore, by setting a protective sleeve 205 at the end face of the protective plate 201, when the cable body 4 is subjected to sudden external force, the cable body 4 pulls the protective sleeve 205, causing the wear-resistant rubber protective sleeve 205 to undergo adaptive deformation and buffer the pulling force. At the same time, due to the roughness of the inner wall of the protective sleeve 205, the friction between the protective sleeve 205 and the cable body 4 is increased, preventing the cable body 4 from shifting when suddenly pulled.

[0043] Example 3, based on Example 2, such as Figures 7-11 As shown, it also includes telescopic blocks 206 and clamping blocks 207; the base plate 1 has a number of sliding grooves 13; each protective plate 201 has a receiving groove 21; each sliding groove 13 has a telescopic block 206 made of thermoplastic elastomer material fixedly connected; each telescopic block 206 has two clamping blocks 207 fixedly connected, and the clamping blocks 207 are in contact with the cable body 4. The clamping blocks 207 slide in the corresponding receiving groove 21 and sliding groove 13, and the clamping blocks 207 are in contact with the corresponding protective plate 201; the protective plate 201 is made of heat-conducting material.

[0044] It also includes a shielding ring 208; the base plate 1 is fixed with several shielding rings 208, and the shielding rings 208 are located on the inner wall of the corresponding wire groove 33.

[0045] Heat dissipation fins are provided on the upper side of the protective plate 201 to increase the heat dissipation area of ​​the protective plate 201, thereby enhancing the heat exchange efficiency between the protective plate 201 and the outside air, and thus improving the heat dissipation effect of the cable body 4.

[0046] Considering that the cable body 4 will generate significant heat after being fixed inside the cable tray 33 in hot weather, leading to poor heat dissipation and potential safety hazards, and that the cable body 4 is at risk of freezing and cracking in low temperatures, to address this issue, after the cable body 4 is placed inside the cable tray 33, a gap remains between the cable body 4 and the inner wall of the cable tray 33. Figure 11 As shown, in low-temperature weather, the clamping block 207 is tightly attached to the cable body 4, sealing the gap between the cable body 4 and the inner wall of the cable trough 33. This prevents the heat generated by the cable body 4 from being transferred to the protective plate 201 through the gap, thus insulating the cable body 4. In high-temperature weather, the heat generated by the cable body 4 is transferred to the thermoplastic elastomer expansion block 206, causing the expansion block 206 to expand and extend. The expansion block 206 then drives the two clamping blocks 207 to move in opposite directions within the sliding groove 13, releasing the clamping blocks 207 from obstructing the gap between the cable body 4 and the inner wall of the cable trough 33. Figure 11 As shown, the heat generated by the cable body 4 is transferred to the protective plate 201 through the gap, and finally the heat generated by the cable body 4 is dissipated to the outside through the heat-conducting protective plate 201, thereby improving the heat dissipation efficiency.

[0047] Considering that when multiple cable bodies 4 are compactly arranged in the cover plate 3, there may be electromagnetic interference between adjacent cable bodies 4, in order to solve this problem, a shielding ring 208 is placed on the inner wall of the cable trough 33 to provide electromagnetic shielding between adjacent cable bodies 4 and reduce the interference between cable bodies 4.
