Description

Technical Field

[0001] The present application relates to the technical field of cable channel protection, and in particular to a cable channel structure with an anti-external damage function. Background Art

[0002] At present, the cabling rate of urban distribution networks is increasing year by year, and the coverage rate of power channels is also increasing accordingly. The power channels of urban distribution networks are mainly divided into four laying methods: direct burial, cable pipes, cable trenches, and cable tunnels. Among them, the direction of the power channel cannot be observed by the naked eye in the direct burial and cable pipe laying methods. This type of channel has a high risk of external damage. In recent years, urban construction such as road widening and subway construction have become the main factors for external damage to power channels. It is difficult to accurately avoid power channels during construction. Cables are often broken due to construction excavation and violent dismantling, causing the entire power line to be out of power, affecting the reliability of the power supply system, and also consuming a lot of human resources to carry out emergency repairs.

[0003] There are two laying methods that are usually vulnerable to damage: direct burial and pipe laying. The tops of these two types of power channels are structures with backfill soil and protective plates, which cannot provide protection when encountering destructive external forces. In the prior art, wire mesh is usually laid in the backfill soil to buffer the destructive external forces, but the gravity of the backfill soil above the wire mesh will cause a longitudinal downward pressure on the wire mesh. Under the influence of this force, the wire mesh is difficult to deform. In addition, the cost of wire mesh is relatively high and its scope of application is limited. Moreover, in the actual operation and maintenance process, the power supply company cannot obtain real-time information about the power channel in a timely manner. There are still cases where the power channel is damaged, resulting in large-scale power outages, or escape after the power channel is damaged. Summary of the invention

[0010] In some embodiments, there are multiple electrical signal generators, and each steel wire in the horizontal channel is connected to a corresponding electrical signal generator.

[0011] In some embodiments, in two adjacent layers of space, the projection of any partition in the upper layer in the lower layer is located between two corresponding partitions in the lower layer, forming a staggered and stacked multi-layer plate structure.

[0012] In some embodiments, the electrical signal generator is a piezoelectric ceramic sensor.

[0013] In some embodiments, the sandwich panels are made of polypropylene and polyethylene.

[0014] On the other hand, a method for constructing a cable channel that is resistant to external damage is provided, which is characterized in that it includes: after placing the cable in the cable channel, performing a first backfilling operation between two adjacent cable working shafts and directly above the cable channel; when the sand is backfilled to above the warning tape, a sandwich panel is arranged, and an electrical signal generator and a wireless transceiver are installed in the cable working shaft; a plurality of horizontal channels are arranged inside the sandwich panel, and a buffer is arranged inside the horizontal channel; after connecting the buffer and the electrical signal generator, performing a second backfilling operation to form a cable channel structure with an anti-external damage function.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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 making creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a cable channel structure with an anti-external damage function, which can solve the problems in the prior art of using a simple wire mesh structure as protection for the cable channel, which has poor effect and high cost, and in the actual operation and maintenance process, the power supply company cannot be informed of the damage of the cable channel in time.

[0027] In the prior art, wire mesh is usually laid in the backfill soil to buffer the destructive external force. However, the gravity of the backfill soil above the wire mesh will cause a vertical downward pressure on the wire mesh. Under the influence of this force, the wire mesh is difficult to deform. In addition, the wire mesh is expensive and has a limited scope of application. Moreover, in the actual operation and maintenance process, the power supply company cannot obtain the real-time damage information of the cable in time, and there are still cases where the cable is damaged, causing large-scale power outages or escaping after the cable is damaged. Then, a device is designed, the structure of which can withstand the vertical downward pressure caused by the backfill soil's own gravity, and secondly, it will not affect the protective effect against destructive external forces, and can use buffers with a wider adaptability and higher cost-effectiveness, similar to the protective effect of wire mesh; secondly, a monitoring component that can be linked with the device is designed. When the buffer in the device is impacted by external force, it drives the monitoring component to generate an electrical signal and send the electrical signal to the power company's monitoring center or related management system, so as to monitor and analyze the safety status of the cable in real time; thereby solving the problems in the prior art of using a simple wire mesh structure as a protective effect for the cable, which is poor and costly, and in the actual operation and maintenance process, the power supply company cannot obtain the information in time when the cable is damaged.

[0028] refer to Figure 1-4 A cable channel structure with an anti-external damage function comprises: a sandwich panel 1, wherein a plurality of horizontal channels are arranged inside, and a buffer is arranged inside the horizontal channel; the sandwich panel 1 is arranged directly above the cable channel 2 and between two adjacent cable working shafts 3; an electric signal generator 5 is installed on the cable working shaft 3 and connected to the buffer, and the electric signal generator 5 is used to generate an electric signal when the sandwich panel 1 is deformed by force; a wireless transceiver 6 is installed on the cable working shaft 3 and is used to receive and send electric signals.

[0029] Through this structural design, the sandwich panel 1 is the main device for preventing the structure from being damaged from the outside, and a plurality of horizontal channels are arranged inside it. Each channel is equipped with a buffer to absorb and disperse the force applied from the outside, so as to prevent the cable channel from being damaged. In the prior art, a steel wire mesh is generally used, which is expensive and has a limited scope of application. Through the structure of the sandwich panel 1, various practical and cost-effective buffers can be matched, and a steel wire rope can be used; and the electric signal generator 5 is installed on the cable working shaft 3, and the electric signal generator 5 is connected to the buffer. When the sandwich panel 1 is deformed by external force, the electric signal generator 5 will generate an electric signal in real time to reflect the state of the sandwich panel 1; the wireless transceiver 6 is also installed on the cable working shaft 3, which is responsible for receiving the electric signal generated by the electric signal generator 5 and transmitting it to the power company. Through wireless technology, remote monitoring and data transmission can be realized to ensure that relevant personnel can obtain the stress condition of the sandwich panel 1 in real time, that is, whether the cable channel 2 is damaged on site.

[0030] When the sandwich panel 1 is affected by external force, the internal buffer will absorb part of the impact force, thereby playing a protective role for the cable channel 2. Secondly, part of the impact will cause the sandwich panel 1 to deform slightly; the electric signal generator 5 generates corresponding electric signals according to the deformation of the sandwich panel 1, and responds to external influences in a timely manner; the wireless transceiver 6 sends the received electric signals to the monitoring center or related management system of the power company, so as to monitor and analyze the safety status of the cable channel 2 in real time. Through the design of the sandwich panel 1 with a new structure and the cooperation with the electric signal generator 5 and the wireless transceiver 6, it has excellent anti-external damage function, can effectively ensure the safe operation of the cable, and improve the reliability of the power system. Thereby solving the problem that in the prior art, the simple wire mesh structure is used as the protection of the cable channel, which has poor effect and high cost, and in the actual operation and maintenance process, the power supply company cannot obtain the information in time when the cable channel is damaged.

[0031] In some preferred embodiments, the buffer is a steel wire 4, which is arranged along the length direction of the horizontal channel and penetrates the horizontal channel.

[0032] Through this structure, the steel wire 4 is used as a buffer to provide high-strength support and reliable pressure resistance. The steel wire 4 has excellent toughness and durability and is a preferred protective material. In combination with the sandwich panel 1, it is more cost-effective than the traditional steel wire mesh, uses less material, and is easy to manufacture and apply on a large scale. The steel wire 4 is arranged along the length direction of the horizontal channel and runs through the entire horizontal channel. This arrangement can evenly disperse the applied force when subjected to external impact, reducing the risk of damage to the cable channel.

[0033] In some preferred embodiments, a pipe 7 penetrating the inner wall of the cable working shaft 3 is provided on the shaft wall, and both ends of the sandwich panel 1 are respectively fixed in the corresponding pipes 7; the electrical signal generator 5 is installed on the inner shaft wall of the cable working shaft 3.

[0034] Through this structural design, the sandwich panel 1 is used as an important protective device, and its two ends are firmly fixed in the pipe 7, which helps to ensure the stability of the sandwich panel 1. The electric signal generator 5 is installed on the inner wall of the cable working shaft 3, so the steel wire 4 arranged in the sandwich panel 1 can pass through the pipe 7 to connect with the electric signal generator 5 arranged on the inner wall. When the sandwich panel 1 is damaged and deformed by external force, the internal steel wire 4 is deformed to drive the electric signal generator 5 connected thereto to generate an electric signal under the force.

[0035] In some preferred embodiments, the sandwich panel 1 includes a top plate 11 and a bottom plate 12; a plurality of partitions 13 perpendicular to the top plate 11 are arranged between the top plate 11 and the bottom plate 12, and the plurality of partitions 13 are arranged at equal intervals to divide the internal space of the sandwich panel 1 into a plurality of horizontal channels.

[0036] Through this structural design, the sandwich panel 1 is composed of a top plate 11 and a bottom plate 12, and a stable frame is formed between the two, which provides support and protection for the entire structure. The horizontal channel formed by the partition 13 is suitable for placing buffers such as steel wires 4, ensuring the neat arrangement and positioning of the steel wires 4, and avoiding the movement and mutual interference of the steel wires 4. This design enhances the structural stability of the sandwich panel 1. A plurality of partitions 13 perpendicular to the top plate are arranged between the top plate 11 and the bottom plate 12. The arrangement of these partitions creates a plurality of horizontal channels, which are mainly used to place the steel wires 4, so that the buffering effect of the steel wires 4 is optimal when damaged by external forces. In addition, the top plate 11 can withstand the longitudinal pressure brought by the backfill soil, and can not affect the buffering effect of the steel wires 4.

[0037] In some preferred embodiments, at least one transverse plate 14 parallel to the top plate 11 is provided between the top plate 11 and the bottom plate 12; the transverse plate 14 evenly divides the internal space of the sandwich panel 1 into multiple layers of space, and a plurality of partitions 13 perpendicular to the transverse plate 14 are evenly arranged in each layer of space, dividing each layer of space into multiple horizontal channels; the electrical signal generator 5 is connected to the steel wire 4 in any layer of space.

[0038] Through this structural design, as mentioned above, the sandwich panel 1 is composed of a top plate 11 and a bottom plate 12, providing a solid frame and support. At least one horizontal plate 14 parallel to the top plate 11 is provided between the top plate 11 and the bottom plate 12. The provision of the horizontal plate 14 not only enhances the stability of the structure, but also evenly divides the internal space of the sandwich panel 1 into multiple layers of space. Through the division of the horizontal plate 14, the internal space of the sandwich panel 1 is divided into multiple independent spaces. With this design, multiple steel wires 4 can be neatly accommodated in different layers at the same time. When the steel wires 4 located in the upper layer are damaged and deformed by external forces, the steel wires 4 located in the lower layer can continue to withstand the remaining external forces to achieve the best protection effect. In this design, the electrical signal generator 5 can be connected to the steel wires 4 in any layer of space. Through this connection method, convenience is provided for the connection, and a flexible connection scheme is provided, which can be adjusted and allocated according to actual changes in demand.

[0039] In some preferred embodiments, there are multiple electrical signal generators 5 , and each steel wire 4 in each horizontal channel is connected to a corresponding electrical signal generator 5 .

[0040] Further design optimization increases the number of electric signal generators 5 to multiple, and each steel wire 4 in the horizontal channel is connected to an electric signal generator 5. This improvement is intended to improve monitoring accuracy and avoid the situation where, when the cable channel 2 is damaged, the deformed steel wire 4 is not connected to the electric signal generator 5, and cannot generate an electric signal and thus cannot be detected, acquired, or sent. The steel wires 4 in each horizontal channel are connected through an independent electric signal generator 5. This one-to-one configuration mode ensures that each steel wire can be fully detected.

[0041] In some preferred embodiments, in two adjacent layers of space, the projection of any partition 13 in the upper layer in the lower layer is located between the two corresponding partitions 13 in the lower layer, forming a staggered and stacked multi-layer plate structure.

[0042] In this embodiment, the partitions 13 in the upper space are no longer arranged to correspond to the lower space, but are arranged in a staggered manner so that the projection of each upper partition 13 falls between two adjacent partitions 13 in the lower space, which is conducive to enhancing the structural stability between the layers. The design of the sandwich panel 1 introduces a staggered and stacked multi-layer plate structure, which is specifically manifested as the projection of any partition 13 in the upper space in the lower space in the two adjacent spaces above and below is located between the two corresponding partitions 13 in the lower space; after the steel wire 4 in the upper space is deformed by external force, the steel wire 4 in the lower space can better withstand the remaining external force, achieving the best protection effect.

[0043] In some preferred embodiments, the electrical signal generator 5 is a piezoelectric ceramic sensor.

[0044] The advantages of the selection of piezoelectric ceramic sensors include: high sensitivity, piezoelectric ceramics can produce sensitive electrical signal responses to external mechanical stress, suitable for the detection of small vibrations and pressure changes; fast response, the sensor has a fast response time, can capture transient signals in real time, suitable for dynamic measurement environments; miniaturization and lightweight, piezoelectric ceramics are small and light, easy to use in various scenarios; low power consumption, piezoelectric ceramic sensors usually have low energy consumption when working, extend the service life of the equipment, and are suitable for battery-powered portable devices. By using piezoelectric ceramic sensors as electrical signal generators5, not only can the detection accuracy and response speed of the system be improved, but also the adaptability and maintainability of the system for various application scenarios can be enhanced.

[0045] In some preferred embodiments, the sandwich panel 1 is made of polypropylene and polyethylene.

[0046] The sandwich panel 1 is made of polypropylene and polyethylene, and its advantages include: lightweight, which is light and easy to carry and install; high strength, which has good compressive strength and impact resistance despite its light weight, can withstand certain external loads, and is suitable for various structural applications; environmental protection, the material is recyclable, meets the requirements of sustainable development, and helps to reduce the environmental burden; cost-effective, compared with other materials, the production cost of this material is low, the cost-effectiveness is high, and it is suitable for large-scale production and application. The use of polypropylene and polyethylene materials to manufacture the sandwich panel 1 not only achieves a good balance between weight and strength, but also has excellent environmental protection characteristics. This design makes the sandwich panel 1 perform well in multiple application fields and has good market prospects and practical value.

[0047] refer to Figure 5 , a method for constructing an anti-external damage cable channel, comprising:

[0048] Step 101, after placing the cable in the cable channel 2, performing the first backfilling operation of sand between two adjacent cable working wells 3 and directly above the cable channel 2;

[0049] The cable is protected by this step, and then the cable channel 2 is filled with backfill sand to hide and protect the cable channel 2;

[0050] Step 102, when the sand is backfilled to above the warning tape 8, the sandwich panel 1 is set, and the electric signal generator 5 and the wireless transceiver 6 are installed in the cable working well 3; a plurality of horizontal channels are provided inside the sandwich panel 1, and buffers are provided inside the horizontal channels.

[0051] Through this step, after the first backfilling operation is completed, the sandwich panel 1 is laid on the top of the warning tape 8, and its two ends are fixed on the cable working well 3; secondly, an electric signal generator 5 and a wireless transceiver 6 are also installed on the cable working well 3, and the buffer parts in the multiple horizontal channels arranged in the sandwich panel 1 cooperate with the electric signal generator 5 and the wireless transceiver 6 to play a monitoring role.

[0052] Step 103: After the buffer and the electric signal generator 5 are connected, a second backfilling operation is performed to form a cable channel structure with an external damage prevention function.

[0053] Through this step, the sandwich panel 1 is also hidden and protected, and after the second backfilling operation is completed, a complete protection and monitoring structure is formed.

[0054] Through this method, the structure constructed by the sandwich panel 1 and its internal buffer can effectively prevent external impact and pressure from damaging the cable channel 2. The cooperation of the electric signal generator 5 and the wireless transceiver 6 facilitates on-site monitoring of the cable channel 2. The entire structure improves the safety of the cable through reasonable design and step-by-step operation.

[0055] The beneficial effects brought by the present invention include:

[0056] The sandwich panel 1 is the main device for preventing the structure from being damaged from the outside, and a plurality of horizontal channels are arranged inside it. Each channel is equipped with a buffer to absorb and disperse the force applied from the outside, so as to prevent the cable channel 2 from being damaged.

When the sandwich panel 1 is deformed by external force, the electric signal generator 5 will generate an electric signal in real time to reflect the state of the sandwich panel 1; the wireless transceiver 6 is also installed on the cable working shaft 3, which is responsible for receiving the electric signal generated by the electric signal generator 5 and transmitting it to the power company. Through wireless technology, remote monitoring and data transmission can be realized to ensure that relevant personnel can obtain the stress condition of the sandwich panel 1 in real time, that is, whether the cable channel 2 is damaged on site. When the sandwich panel 1 is affected by external force, the internal buffer will absorb part of the impact force, thereby playing a protective role for the cable channel 2. Secondly, part of the impact will cause the sandwich panel 1 to deform slightly; the electric signal generator 5 generates corresponding electric signals according to the deformation of the sandwich panel 1, and responds to external influences in time; the wireless transceiver 6 sends the received electric signals to the monitoring center or related management system of the power company, so as to monitor and analyze the safety status of the cable channel 2 in real time.

Thereby solving the problem that in the prior art, the simple steel wire mesh structure is used as the protection effect of the cable is poor and the cost is high, and in the actual operation and maintenance process, the power supply company cannot obtain the information in time when the cable is damaged. .
