Description

Technical Field

[0001] This application relates to the field of power transmission technology, and more particularly to a drainage system for draining cable channels. Background Technology

[0002] Underground cable tunnels are the arteries of modern urban power transmission. Their core function is to safely and efficiently organize and manage underground cable networks, ensuring a stable power supply while also considering urban space and safety requirements. With accelerated urbanization and the expansion of paved areas, rainwater cannot infiltrate during short-term heavy rainfall or continuous downpours, instead forming surface runoff. This runoff can backflow into underground cable tunnels through poorly sealed manhole covers or cable penetrations, causing water accumulation that poses a serious threat to stable power supply. Therefore, it is necessary to implement a drainage system to remove accumulated water from underground cable tunnels and eliminate this threat to power stability.

[0003] In existing technologies, for indoor water accumulation in substations or power distribution rooms, a drainage robot with its own water pump is used to drain the indoor water.

[0004] However, in the above methods, the underground cable tunnel is too narrow, so the drainage robot cannot directly enter the underground cable tunnel to perform the drainage task. Summary of the Invention

[0044] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] In existing technologies, drainage robots are typically used to drain water from substations or power distribution rooms. However, these robots are not suitable for special scenarios such as underground cable tunnels. A drainage robot is an integrated working platform, reaching 2 to 3 meters in length, weighing several tons, and measuring 1.5 to 1.8 meters in width. Due to the confined space in underground cable tunnels, drainage robots, being too large, cannot enter these tunnels to perform drainage tasks.

[0047] In response to the problems existing in the prior art, the inventors discovered during their research on drainage systems for cable tunnels that by placing a submersible pump with a width of only 25cm deep inside the tunnel, and then using a drainage robot located at the entrance of the underground cable tunnel to supply high-pressure hydraulic oil to the submersible pump via hydraulic oil pipes, the submersible pump can be driven to drain the water accumulated in the underground cable tunnel, thereby eliminating the threat of water accumulation in the tunnel to the stable power supply.

[0048] Based on the above-mentioned inventive concept, the drainage scheme for cable channel drainage of this application was designed.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] Figure 1 The structural schematic diagram of the drainage system for cable channel drainage provided in this application Figure 1 ,like Figure 1As shown, the system includes: a drainage robot 1, a hydraulic oil pipe 2, a submersible drainage pump 3, and a transport hose 4; the drainage robot 1 is installed at the entrance of the underground cable channel, and the submersible drainage pump 3 is installed at a preset position inside the underground cable channel, where the water in the channel is 5; the drainage robot 1 is connected to the submersible drainage pump 3 via the hydraulic oil pipe 2, and the submersible drainage pump 3 is connected to the transport hose 4; the drainage robot 1 is used to provide high-pressure hydraulic oil to the submersible drainage pump 3 through the hydraulic oil pipe 2, so as to control the submersible drainage pump 3 to discharge the water in the channel 5 inside the underground cable channel through the transport hose 4.

[0051] For example, the width of the drainage robot 1 is approximately between 1.5 meters and 1.8 meters, though this may vary depending on the model and design. The length of the drainage robot 1 can reach 2 to 3 meters, and its weight can reach several tons. In this embodiment, the total mass of the drainage robot 1 may reach 3850 kg.

[0052] For example, hydraulic hose 2 is the blood vessel that transmits power, responsible for delivering high-pressure hydraulic oil. The pressure-bearing capacity of hydraulic hose 2 mainly depends on its internal steel wire reinforcement layer, which acts as the skeleton of the pipe. There are two main processes for the steel wire reinforcement layer: steel wire braiding, where steel wires are cross-woven, provides good flexibility; and steel wire winding, where steel wires are spirally wound alternately, offering higher resistance to pulse pressure and burst pressure. The higher the number of layers, the stronger the pressure resistance. For example, a two-layer steel wire braided hose has approximately 30% higher pressure resistance than a single-layer hose, making it suitable for medium-pressure applications; while a four-layer steel wire winding hose is specifically designed for harsh conditions involving high pressure and high pulses, such as the hydraulic main pump circuit of construction machinery.

[0053] In areas with confined spaces and frequent bending, hydraulic hoses with good flexibility should be selected, and the minimum bending radius should be ensured.

[0054] Precautions for the installation and maintenance of hydraulic hose 2: First, hydraulic hose 2 should not be in a state of torsional deformation during installation. The axis of the joint should be as close as possible to the plane of motion to avoid damage to hydraulic hose 2. Second, the bending radius of hydraulic hose 2 should not be too small, generally not less than the standard specified value, and there should be a straight section at the joint that is more than twice the outer diameter of the pipe. Third, hydraulic hose 2 will shrink by about 3% to 4% under pressure. It should not be in a taut state during installation and should be kept loose. Fourth, hydraulic hose 2 should avoid contact and friction with sharp corners of machinery. If necessary, protective devices such as springs or hydraulic hose clamps should be used. At the same time, it should be kept away from heat sources as much as possible.

[0055] For example, a 25 cm wide hydraulic submersible pump 3 is connected to a drainage robot 1 via a high-pressure oil pipe 2. The high-pressure hydraulic oil generated by the drainage robot 1 flows into the hydraulic motor inside the submersible pump 3. The hydraulic motor drives the impeller shaft, causing the impeller to rotate at high speed, typically reaching 6000 rpm. The rotating impeller causes the water in the channel 5 to move in a circular motion. Under the action of centrifugal force, the water in the channel 5 is thrown towards the edge of the impeller, forming a low-pressure area in the center of the submersible pump 3. The thrown-out water in the channel 5 is pressurized inside the pump casing and finally transported to the drainage point on the road surface through the drain outlet and the transport hose 4.

[0056] The embodiments of this application provide a drainage system for cable tunnel drainage. Through the coordinated operation of a drainage robot 1, hydraulic oil pipe 2, drainage submersible pump 3, and transport water belt 4 at the entrance of the underground cable tunnel, the water 5 accumulated in the underground cable tunnel is discharged to the drainage point on the ground, thereby achieving a stable power supply.

[0057] Figure 2 The structural schematic diagram of the drainage system for cable channel drainage provided in this application Figure 2 ,like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, a drainage system for draining cable channels will be described in detail.

[0058] In one example, the drainage machine 1 is equipped with a fuel engine, a hydraulic pump, and a hydraulic oil tank; wherein, the fuel engine is connected to the hydraulic pump, and the hydraulic pump is connected to the hydraulic oil tank; the fuel engine is used to drive the hydraulic pump to pressurize the hydraulic oil in the hydraulic oil tank so as to output high-pressure hydraulic oil to the drainage submersible pump 3.

[0059] For example, the internal combustion engine used in this embodiment can be a gasoline engine, which is a precision device that converts the chemical energy of fuel into mechanical power. An internal combustion engine follows a four-stroke cycle, including four steps: intake, compression, power, and exhaust.

[0060] This embodiment recommends using a diesel engine. Both gasoline and diesel engines are excellent internal combustion engines; the former is ignited by spark plugs; the latter generates high temperatures through high-pressure compressed air, causing it to ignite spontaneously, without an ignition system; the former is generally lighter, has higher speeds, and less noise and vibration; the latter has a higher compression ratio, better thermal efficiency, greater torque, and is more fuel-efficient; the latter has a robust structure, longer lifespan, and relatively simpler maintenance.

[0061] For example, the hydraulic pump is the power component of the hydraulic system. It is driven by a fuel engine to pressurize the hydraulic oil in the hydraulic oil tank and output high-pressure hydraulic oil to the submersible pump 3.

[0062] For example, the operation of a hydraulic pump is based on the change of sealed volume. Through the movement of internal parts, such as plungers, gears, or vanes, the volume of the pump chamber changes periodically: when the volume increases, a vacuum is created, drawing hydraulic oil from the hydraulic tank; when the volume decreases, the hydraulic oil is squeezed, forming high-pressure hydraulic oil and being discharged. Because pressure is generated by changes in volume, hydraulic pumps are also called positive displacement pumps.

[0063] This embodiment explains in detail the components of the drainage robot 1, making it possible for the drainage robot 1 to provide high-pressure hydraulic oil to the drainage submersible pump 3.

[0064] In one example, the drainage robot 1 is equipped with a movable chassis; the fuel engine is mounted on the movable chassis via a shock-absorbing rubber mount.

[0065] For example, the mobile chassis is a tracked high-access chassis made of high-strength steel, such as 45# steel, treated with electrophoresis and high-temperature baking paint, exhibiting excellent corrosion resistance. The mobile chassis features a portal-type bottom design, providing space for the installation of the main water pump. The track truss includes an upper truss and a lower truss, connected by adjustable elongated holes for easy disassembly, maintenance, and tension adjustment.

[0066] For example, a shock-absorbing rubber mount is a protective device used in engineering structures. It absorbs and dissipates vibration energy through the elastic deformation of rubber material, thereby reducing the impact of vibration or impact on a fuel engine.

[0067] The core of shock-absorbing rubber mounts lies in utilizing the unique high elastic deformation of rubber to dissipate energy. When subjected to external impact or vibration, the rubber layer undergoes shear, compression, or tensile deformation, converting the mechanical energy generated by the internal combustion engine into heat energy and dissipating it, thereby significantly reducing the energy transmitted to the movable chassis.

[0068] This embodiment can extend the lifespan of the internal combustion engine and the mobile chassis.

[0069] In one example, the hydraulic oil tank is located at the bottom of the movable chassis; water flowing through the channel 5 at the bottom of the movable chassis cools the hydraulic oil tank.

[0070] For example, when a hydraulic system is working, the hydraulic pump converts mechanical energy into the pressure energy of the hydraulic oil. This energy conversion process is not 100% efficient and inevitably produces mechanical losses, pressure losses, and volumetric losses. The lost energy is almost entirely converted into heat energy, which directly heats the hydraulic oil, thereby raising the temperature of the hydraulic oil tank.

[0071] For example, common heat generation scenarios include: after the hydraulic pump wears out, high-pressure hydraulic oil leaks back into the hydraulic oil tank, which generates a lot of heat; when the system pressure reaches the set value, the relief valve opens, and the excess high-pressure hydraulic oil overflows back into the hydraulic oil tank, a process that converts hydraulic energy into heat energy.

[0072] For example, the hydraulic system is a closed loop. The high-pressure hydraulic oil heated during operation will continuously flow back to the hydraulic oil tank through the return oil line. After the high-temperature high-pressure hydraulic oil flows into the hydraulic oil tank, it will cause the temperature of the hydraulic oil tank to rise.

[0073] For example, the high-pressure hydraulic oil comes into contact with the inner wall of the hydraulic oil tank, directly transferring heat to the metal wall.

[0074] This embodiment can extend the life of the hydraulic oil tank and improve the working efficiency of the drainage submersible pump 3.

[0075] In one example, a protective frame is provided on the movable chassis, the frame including side plates; the side plates are used to guide the cooling airflow of the fuel engine.

[0076] For example, the protective frame includes bent tubes and side panels.

[0077] For example, a U-shaped combination of side plates is provided on both sides and the rear of the fuel engine. When the cold airflow blown out from the underground cable channel passes through the drainage robot 1, the cold airflow blocked by the side plates will cool the fuel engine.

[0078] For example, the protective frame is also equipped with a sealed electrical installation compartment to achieve waterproof protection for electrical components.

[0079] This embodiment is another typical example of utilizing existing environmental conditions to perform cooling functions. This design can extend the life of a fuel engine and improve its working efficiency.

[0080] In one example, a hydraulic valve block assembly 10 is provided on the protective frame; wherein, the hydraulic oil pipe 2 is connected to the hydraulic pump through the hydraulic valve block assembly 10; the hydraulic valve block assembly 10 is used to control the flow rate of the high-pressure hydraulic oil.

[0081] For example, the hydraulic valve block assembly 10 is the "control hub" of the hydraulic system. Through its ingenious integrated design, it highly concentrates various hydraulic valves, connection channels and auxiliary components that are scattered in the system into one block, thereby realizing comprehensive control of the flow of high-pressure hydraulic oil.

[0082] In this embodiment, the flow rate of high-pressure hydraulic oil can be flexibly controlled by the hydraulic valve block assembly 10 according to the amount of water accumulation in the channel 5.

[0083] In one example, an electrochemical oxygen sensor 8 is installed on the protective frame; the electrochemical oxygen sensor 8 is used to detect the oxygen concentration in the water-filled area within the underground cable tunnel.

[0084] For example, when the oxygen concentration is below 19.5%, the system triggers a remote alarm to remind staff to take ventilation measures.

[0085] For example, the low oxygen concentration in underground cable tunnels can be mainly due to the following reasons:

[0086] First, the "dead zone" of air circulation: Underground cable tunnels are typical long and narrow underground structures. Even with open entrances, it is difficult for fresh air to naturally convect deep into the tunnel. The area near the entrance may become a "dead zone" of air circulation, where the dense, low-oxygen air accumulated inside does not easily dissipate, and fresh air is also difficult to inject effectively, thus creating a low-oxygen area at the entrance.

[0087] Secondly, harmful gases accumulate: During operation, the insulation material (such as XLPE cross-linked polyethylene) of the cable may decompose at high temperatures, producing gases such as methane. Some older oil-filled cables may also release trace amounts of insulating oil gas. Simultaneously, bacteria growing within the cable channel consume oxygen, and the decomposition of organic matter by microorganisms may also produce toxic gases such as carbon monoxide. These gases may accumulate at the inlet due to density differences or poor air circulation, directly diluting or replacing oxygen.

[0088] Third, the "chimney effect": If a passage has multiple exits and a height difference exists, when the temperature inside the passage is higher than the outside, an upward thermal pressure will be created, i.e., the "chimney effect." This may cause the entrance to become an area where airflow is relatively stagnant or even where air replenishment is poor, which is not conducive to oxygen replenishment.

[0089] Low oxygen concentration at the entrance is a safety hazard that cannot be ignored. Generally, an air oxygen content below 19.5% (by volume) is considered an oxygen-deficient environment, which may pose a direct threat to the lives of workers.

[0090] This embodiment ensures the safety of staff.

[0091] In one example, the drainage robot 1 is equipped with a main water pump; the main water pump is used to drain indoor water in a substation or power distribution room, driven by a fuel engine.

[0092] For example, a drainage robot 1 with a width of only 1.5 meters can adapt to the substation scenario. The interior of a substation usually has clearly defined equipment room passages and transportation passages. With a common passage width of about 3 meters, the drainage robot 1 can easily pass through and complete actions such as turning and U-turns.

[0093] For example, the climbing ability of the drainage robot 1 also enables it to cope with the slopes commonly found in substations.

[0094] For example, in a power distribution room, the equipment layout is more compact, and the smaller length and width of the drainage robot 1 means that it can be deployed in limited open space, such as parked in a passage between two rows of switch cabinets to perform its work, without seriously obstructing the maintenance passage.

[0095] This embodiment ensures that the application has strong adaptability to various scenarios.

[0096] In one example, the system also includes a remote control device; the drainage robot 1 is equipped with an electric field sensor 9 and a water quality sensor; the electric field sensor 9 and the water quality sensor are wirelessly connected to the remote control device; the electric field sensor 9 is used to collect the electric field strength of the water accumulation area in the underground cable channel; the water quality sensor is used to collect the water properties data of the water accumulation area in the underground cable channel; the remote control device is used to acquire the electric field strength and water properties data, and determine the degree of damage to the underground cable based on the electric field strength and water properties data.

[0097] For example, the remote control device is wirelessly connected to the electric field sensor 9 and the water quality sensor via 4G / 5G wireless communication technology. The remote control device can remotely control the movement of the drainage robot 1, start and stop drainage, and adjust drainage parameters. The remote control device also has an interface for connecting to the power grid operation and maintenance system, supporting collaborative operation command.

[0098] For example, electric field sensor 9 detects the electric field strength in the water accumulation area within the underground cable tunnel in real time, while water quality sensor detects the properties of the accumulated water in real time. When electric field sensor 9 detects an electric field strength indicating leakage, the remote control device immediately triggers an audible and visual alarm. Continuing to monitor the properties of the accumulated water, when data indicating acidic water quality is detected, the remote control device determines the extent of damage to the underground cable to alert personnel for repairs.

[0099] The properties of the water include the pH of channel water 5, the conductivity of channel water 5, and the turbidity of channel water 5.

[0100] pH of Channel Water 5: This index measures the activity of hydrogen atoms in Channel Water 5, used to determine its acidity or alkalinity. This value is obtained by mathematically processing the hydrogen ion concentration, specifically expressed as the negative common logarithm of hydrogen ion activity. A pH < 7 indicates that Channel Water 5 is acidic, possibly due to dissolved carbon dioxide, or contamination with acidic industrial wastewater or soil seepage containing large amounts of humus. A pH = 7 indicates that Channel Water 5 is neutral, theoretically pure water (generally impossible). A pH > 7 indicates that Channel Water 5 is alkaline, possibly due to contamination with alkaline industrial wastewater or domestic sewage, or increased alkalinity due to the consumption of carbon dioxide during algal blooms.

[0101] The conductivity of channel water 5 is a physical parameter that measures the conductivity of channel water 5. It directly reflects the total concentration of dissolved electrolytes (mainly various ions) in the water. It measures the strength of the water's electrical conductivity. A higher conductivity indicates better conductivity and more dissolved ionic impurities in the water. Higher conductivity also indicates higher salt content or impurities. The unit is Siemens per meter (S / m).

[0102] The turbidity of the channel water 5 is a physical indicator measuring its degree of turbidity. It describes the obstruction or scattering of light by suspended particulate matter in the channel water 5. Although turbidity can indirectly reflect the content of suspended matter in the channel water 5, the two are not a simple linear relationship. For example, the same weight of fine clay particles will result in a much higher turbidity in the water sample than coarse sand particles because smaller particles have a stronger light scattering effect. Therefore, turbidity is an independent water quality indicator and cannot be directly equated with the weight concentration of suspended matter. Turbidity is one of the most intuitive water quality indicators. High turbidity usually means that the water body may be polluted, affecting sensory perception, and may carry microorganisms such as bacteria and viruses. In water treatment, reducing turbidity can also effectively remove some pathogens. High turbidity reduces the depth of sunlight entering the water body, affecting the photosynthesis of aquatic plants, and may also affect the respiration of aquatic organisms (such as fish).

[0103] This embodiment can determine whether underground cables are damaged and the severity of the damage.

[0104] In one example, the system also includes a trailer 6 connected to the drainage robot 1; the trailer 6 is used to carry a spare fuel tank 7 and a transport hose 4.

[0105] For example, the trailer 6 is a movable trailer 6 with its own wheels. The trailer 6 has a cargo box for carrying a spare fuel tank 7 and a water hose 4.

[0106] The backup fuel tank 7 is an auxiliary device used to store extra fuel, primarily for extending driving range or as an emergency reserve.

[0107] The transport water hose 4 is a flexible pipe used to transport water 5 in the channel. Its core design goal is to transport the water 5 in the channel safely and efficiently under pressure.

[0108] For example, the transport hose 4 is not a single-layer hose; it includes an inner lining layer: this layer is in direct contact with the transported medium and requires a smooth surface to reduce flow resistance, and is sealed and corrosion-resistant using materials such as rubber or polyurethane. A reinforcing layer: this is crucial for pressure resistance and is typically made of high-strength fibers such as polyester or linen, woven together to allow the hose to withstand high internal pressure without breaking. Connectors: metal connectors are installed at both ends of the hose for quick and reliable connection to other hoses, pumps, or jetting devices; preventing detachment and leakage is a key design consideration.

[0109] This embodiment increases the versatility of the drainage system and ensures that the system can perform drainage tasks for a long time until the drainage task is completed.

[0110] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
