Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a prefabricated module for the intersection of a power cable and a control cable. Background Art

[0002] Cable trenches are underground pipes used to place and protect cable facilities. They are essential infrastructure in power plants, substations, municipal projects, and large factories and mines. However, due to terrain or design factors, water easily accumulates in cable trenches during heavy rain or rainy seasons. If the water level is too high, the cables in the trenches will be immersed in water for a long time, causing corrosion. This will not only damage the insulation of the cables and affect their lifespan, but also cause bursting of the cables due to water ingress in severe cases. This is particularly true when two different cable trenches, the power cable and the control cable, intersect.

[0003] Existing technical solutions: For this situation, the deeper cable trench is usually passed through the bottom of the shallower cable trench in the form of a drainage pipe or culvert at the intersection node, but such an arrangement structure still has the disadvantages of complex construction, difficult drainage, and troublesome cable laying in the deeper cable trench. There are also concrete cast cross structure arrangements. Although this structure solves the problem of cable cross wiring to a certain extent, it uses a fixed structure with poor flexibility. If there are changes in subsequent cable wiring, it will be difficult to implement. In addition, the cost of concrete casting is too high and the construction is complicated. For this reason, it is necessary to develop a prefabricated module for the intersection of power cables and control cables to solve this problem. The module needs to be easy to disassemble and assemble, and the height of the cable trough can be adjusted according to actual conditions. At the same time, the preparation material must also take into account the characteristics of waterproofing, insulation, wear resistance, and economy. We propose a prefabricated module for the intersection of power cables and control cables. Summary of the invention

[0015] The present invention provides a prefabricated module for the intersection of power cables and control cables. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The prefabricated mold for the intersection of the power cable and the control cable. The prefabricated module for the intersection of the power cable and the control cable is composed of a first support frame, a second support frame, a third support frame, a fourth support frame, a first support bakelite board, a second support bakelite board, an upper control cable support assembly and a lower power cable support assembly during assembly.

[0017] 2. The intersection of the power cable and the control cable is prefabricated, in which each plate and the angle steel frame are fixed by through bolts. If disassembly is required later, only the bolts need to be unscrewed. The first supporting bakelite board and the second supporting bakelite board only play a supporting and isolating role, so that the first supporting bakelite board, the second supporting bakelite board and the formed cable trench have a certain height difference, which is convenient for water drainage in the cable trench, avoiding the power cable and the control cable from being immersed in rainwater, and avoiding the cable from being immersed in water for a long time and corrosion.

In addition, the control bakelite board or the power bakelite board can be appropriately tilted and positioned and fixed according to the actual slope of the cable trench.

[0038] Reference Figure 1-5 The first supporting bakelite board 1021 is fixedly installed between the first supporting frame 1011 and the fourth supporting frame 1014 by bolts, the second supporting bakelite board 1022 is fixedly installed between the second supporting frame 1012 and the third supporting frame 1013 by bolts, the first connecting member 1032 and the first mounting member 1045 are fixedly installed between the second supporting frame 1012 and the third supporting frame 1013 by bolts, the second connecting member 1034 and the second mounting member 1043 are fixedly installed between the first supporting frame 1011 and the fourth supporting frame 1014 by bolts, and the third connecting member 1033 and the third mounting member 1044 are fixedly installed by bolts Installed between the first support frame 1011 and the second support frame 1012, the fourth connecting member 1035 and the fourth mounting member 1042 are fixedly installed between the third support frame 1013 and the fourth support frame 1014 by bolts, the control bakelite board 1031 is fixed to the first connecting member 1032, the second connecting member 1034, the third connecting member 1033 and the fourth connecting member 1035 by screws respectively, the power bakelite board 1041 is fixed to the first mounting member 1045, the second mounting member 1043, the third mounting member 1044 and the fourth mounting member 1042 by screws respectively, and the power bakelite board 1041 is arranged below the control bakelite board 1031.

[0039] This prefabricated module for the intersection of power cables and control cables is assembled by a first support frame 1011, a second support frame 1012, a third support frame 1013, a fourth support frame 1014, a first support bakelite board 1021, a second support bakelite board 1022, an upper control cable support assembly and a lower power cable support assembly, the control cable support assembly is composed of a control bakelite board 1031, a first connector 1032, a second connector 1034, a third connector 1033 and a fourth connector 1035, and the power cable support assembly is composed of a power bakelite board 1041, a first mounting member 1045, a second mounting member 1043, a third mounting member 1044 and a fourth mounting member 1042, which are assembled by bolts to form respective channels for the power cable 301 and the control cable 201, and the cross influence can be avoided through the respective channels;

[0040] Each plate is fixed to the frame 101 of the angle steel by through bolts. If it is necessary to disassemble it later, just unscrew the bolts. The prefabricated module is based on the height difference between the power cable trench (400*400) and the control cable trench (800*800). The power cable trench is taken as the reference trench, and the channels of the power and control cables are designed to form a channel frame that does not intersect and touch each other, providing a corresponding safe routing channel for the cable. Due to the height difference of the cable trench of the two cables, the space left below is not used for routing, that is, the first supporting bakelite board 1021 and the second supporting bakelite board 1022 only play a supporting and isolating role, so that the first supporting bakelite board 1021 and the second supporting bakelite board 1022 have a certain height difference with the formed cable trench, which is convenient for the cable trench to run water, avoid the power cable 301 and the control cable 201 from being immersed in rainwater, and avoid the cable from being immersed in water for a long time and corroded. It will not only not damage the insulation of the cable and affect its life, but also will not cause bursting due to water ingress. This is particularly true when two different cable trenches, the power cable and the control cable, intersect;

[0041] At the same time, since there are multiple fixing grooves on the L-shaped angle steel, the height of the control bakelite board 1031 or the power bakelite board 1041 can be freely adjusted as needed during on-site installation, which is convenient for adaptation and adjustment. In addition, the control bakelite board 1031 or the power bakelite board 1041 can be appropriately tilted and positioned and fixed according to the actual slope of the cable trench. This can effectively prevent rainwater from accumulating in the power cable 301 and the control cable 201, thereby causing corrosion to the cables.

[0042] Reference Figure 4-5The frame 101 also includes a first isolating bakelite board 1023 and a second isolating bakelite board 1024. The first isolating bakelite board 1023 is fixedly installed between the first support frame 1011 and the second support frame 1012 by bolts, and the second isolating bakelite board 1024 is fixedly installed between the third support frame 1013 and the fourth support frame 1014 by bolts.

[0043] The first insulating bakelite board 1023 and the second insulating bakelite board 1024 can improve the connection strength of the frame 101, and the first insulating bakelite board 1023 and the second insulating bakelite board 1024 can block the control cable 201 to prevent the control cable 201 from detaching from the frame 101.

[0044] Reference Figure 4-5 The first supporting bakelite board 1021, the second supporting bakelite board 1022, the control bakelite board 1031, the power bakelite board 1041, the first isolating bakelite board 1023 and the second isolating bakelite board 1024 all adopt a three-layer structure, which includes bakelite boards of inner and outer layers and phenolic laminated paperboard of the middle layer.

[0045] The first supporting bakelite board 1021, the second supporting bakelite board 1022, the control bakelite board 1031, the power bakelite board 1041, the first isolating bakelite board 1023 and the second isolating bakelite board 1024 on the frame 101 all adopt a three-layer structure, which is a bakelite board with inner and outer layers and a phenolic laminated paperboard in the middle layer. The phenolic laminated paperboard is a bakelite board made of high-quality bleached wood building paper and cotton linter paper as reinforcements, and a phenolic resin made by reacting high-purity, fully synthetic petrochemical raw materials as a resin adhesive. The bakelite board made of this material has good electrical properties at room temperature, good mechanical processing performance, a specific gravity of about 1.45, and a warpage of ≤3‰. Once heated and formed, it solidifies and cannot be molded into other things. Therefore, it has the characteristics of non-absorbent, non-conductive, high temperature resistant, high strength, and wear resistance. At the same time, the raw material price of the bakelite board is low, only half the price of ABS plastic board, and the cost is even lower.

[0046] Example 2, refer to Figure 6 The difference between this embodiment and the first embodiment is that the outer surfaces of the first isolating bakelite board 1023 and the second isolating bakelite board 1024 are both provided with a plurality of water holes 401, and the water holes 401 provided can facilitate the drainage of the control cable groove of the control cable 201, thereby preventing the first isolating bakelite board 1023 and the second isolating bakelite board 1024 from affecting the drainage operation of the control cable groove, thereby improving the practicality of the present device.

[0047] Example 3, refer to Figure 7-10The difference between this embodiment 3 and the embodiments 1 and 2 is that the control bakelite board 1031 and the power bakelite board 1041 are both fixed with an isolation wire clamp body 501 by bolts, and the isolation wire frame body 501 includes a wire clamp plate 5015, and the wire clamp plate 5015 is provided with a first wire clamp channel 5011, a second wire clamp channel 5012 and a third wire clamp channel 5013.

[0048] In order to facilitate the wiring operation and avoid the entanglement of adjacent cables, an isolation wire clamp body 501 is added. The isolation wire frame body 501 includes a wire clamp plate 5015, and the wire clamp plate 5015 is provided with a first wire clamping channel 5011, a second wire clamping channel 5012 and a third wire clamping channel 5013. The first wire clamping channel 5011, the second wire clamping channel 5012 and the third wire clamping channel 5013 can separate a group of three-phase electrical cables to avoid the entanglement of adjacent wires and the contact of adjacent wires to affect the heat dissipation of the wires. The first wire clamping channel 5011, the second wire clamping channel 5012 and the third wire clamping channel 5013 are used to clamp and position the wires, which is convenient for personnel to organize three-phase electrical cables or other cables.

[0049] Reference Figure 7-10 In order to increase the clamping effect of the isolation wire frame 501 on the cable, the present structure is proposed. Specifically, a cavity 5017 is formed in the inner middle of the wire clamp plate 5015, and a sleeve 5018 is fixedly installed inside the cavity 5017. Two groups of first clamp plates 5025 are arranged on the first clamping channel 5011, and two groups of second clamp plates 5023 are arranged on the second clamping channel 5012. Two groups of third clamp plates 5020 are arranged on the third clamping channel 5013. The inner sides of the first clamp plate 5025, the second clamp plate 5023 and the third clamp plate 5020 are all fixedly connected with a connecting rod. The connecting column 5021 slides into the interior of the sleeve 5018, and the outer surface of the connecting column 5021 is covered with a return spring 5022, the end of the return spring 5022 is fixedly connected to the cavity 5017, and the end of the return spring 5022 away from the cavity 5017 is fixedly connected to the outer surface of the sleeve 5018, both ends of the sleeve 5018 are threaded with matching bolts 5019, the end of the matching bolt 5019 is rotatably connected to a conical component 5024, and the end of the matching bolt 5019 away from the conical component 5024 is fixedly connected to a hexagonal cap.

[0050] When it is necessary to increase the clamping effect of the cable, first clamp the cable into the first clamping channel 5011, the second clamping channel 5012 and the third clamping channel 5013, and then rotate the hexagonal cap with an external tool, which will drive the matching bolt 5019 to rotate, and the matching bolt 5019 will drive its tapered part 5024 to move inwardly of the wire clamp plate 5015, and the tapered part 5024 will squeeze the corresponding three groups of connecting columns 5021, and the three groups of connecting columns 5021 will move outward at the same time, and the reset spring 5024 will be pressed against the corresponding three groups of connecting columns 5021. 022 will be compressed, and the first clamping plate 5025, the second clamping plate 5023 and the third clamping plate 5020 will all move into their corresponding wire clamping channels, thereby cooperating to position and clamp the corresponding cable. When it is necessary to contact the positioning of the cable, the matching bolt 5019 can be rotated outward, and the conical part 5024 will be separated from the current connecting column 5021. Under the action of the reset spring 5022, the first clamping plate 5025, the second clamping plate 5023 and the third clamping plate 5020 will be separated from the current wire clamping channel, thereby releasing the positioning of the cable.

[0051] Working principle: This prefabricated module for the intersection of power cable and control cable is assembled by first support frame 1011, second support frame 1012, third support frame 1013, fourth support frame 1014, first support bakelite board 1021, second support bakelite board 1022, upper control cable support assembly and lower power cable support assembly, control cable support assembly is composed of control bakelite board 1031, first connector 1032, second connector 1034, third connector 1033 and fourth connector 1035, power cable support assembly is composed of power bakelite board 1041, first mounting member 1045, second mounting member 1043, third mounting member 1044 and fourth mounting member 1042 which are assembled by bolts to form respective channels of power cable 301 and control cable 201, and cross influence can be avoided through respective channels;

[0052] Each plate is fixed to the frame 101 of the angle steel by through bolts. If it is necessary to disassemble it later, just unscrew the bolts. The prefabricated module is based on the height difference between the power cable trench (400*400) and the control cable trench (800*800). The power cable trench is taken as the reference trench, and the channels of the power and control cables are designed to form a channel frame that does not intersect and touch each other, providing a corresponding safe routing channel for the cable. Due to the height difference of the cable trench of the two cables, the space left below is not used for routing, that is, the first supporting bakelite board 1021 and the second supporting bakelite board 1022 only play a supporting and isolating role, so that the first supporting bakelite board 1021 and the second supporting bakelite board 1022 have a certain height difference with the formed cable trench, which is convenient for the cable trench to run water, avoid the power cable 301 and the control cable 201 from being immersed in rainwater, and avoid the cable from being immersed in water for a long time and corroded. It will not only not damage the insulation of the cable and affect its life, but also will not cause bursting due to water ingress. This is particularly true when two different cable trenches, the power cable and the control cable, intersect;

[0053] At the same time, since there are multiple fixing grooves on the L-shaped angle steel, the height of the control bakelite board 1031 or the power bakelite board 1041 can be freely adjusted as needed during on-site installation, which is convenient for adaptation and adjustment. In addition, the control bakelite board 1031 or the power bakelite board 1041 can be appropriately tilted and positioned and fixed according to the actual slope of the cable trench, which can effectively prevent rainwater from accumulating in the power cable line 301 and the control cable line 201, thereby causing corrosion to the cables;

[0054] A group of three-phase electrical cables can be separated by the first wire clamping channel 5011, the second wire clamping channel 5012 and the third wire clamping channel 5013 to avoid entanglement of adjacent wires and avoid contact between adjacent wires that affects the heat dissipation of the wires. The first wire clamping channel 5011, the second wire clamping channel 5012 and the third wire clamping channel 5013 are used to clamp and position the cables, which is convenient for personnel to manage three-phase electrical cables or other cables. When it is necessary to increase the clamping effect of the cable, first insert the cable into the first wire clamping channel 5011, the second wire clamping channel 5012 and the third wire clamping channel 5013, and then rotate the hexagonal cap through an external tool. When the hexagonal cap rotates, it will drive the matching bolt 5019 to rotate, and when the matching bolt 5019 rotates, it will drive its cone The conical part 5024 moves toward the inside of the wire clamp plate 5015. At this time, the conical part 5024 will squeeze the corresponding three groups of connecting columns 5021, and the three groups of connecting columns 5021 will move outward at the same time. The reset spring 5022 will be compressed, and the first clamp plate 5025, the second clamp plate 5023 and the third clamp plate 5020 will all move toward their corresponding wire clamping channels, thereby cooperating to position and clamp the corresponding cable. When it is necessary to contact the positioning of the cable, the matching bolt 5019 can be rotated outward, and the conical part 5024 will be separated from the current connecting column 5021. Under the action of the reset spring 5022, the first clamp plate 5025, the second clamp plate 5023 and the third clamp plate 5020 will be separated from the current wire clamping channel, thereby releasing the positioning of the cable.
