Description

Technical Field

[0001] This application relates to the field of manual bored pile construction technology, and in particular to an integrated vehicle battery water cooling system for manual bored piles. Background Technology

[0002] Power towers are trapezoidal or triangular structures, typically 25-40 meters high, with a steel frame structure. They are mostly built near power plants and substations in the field. They are important facilities for the power sector, providing overhead power lines with protection and support. The design, manufacture, installation, maintenance, and quality inspection of power towers are crucial for the operation and development of modern power systems.

[0003] Power towers require a foundation for support. Commonly used foundations are manually excavated bored piles. In areas with abundant rock strata, water-jet drilling is often employed for excavation. Water-jet drilling involves using a concrete core drill to extract cylindrical rock cores along the outer circumference of the pile foundation, creating an open surface on the outer circumference. The remaining rock core is then divided into sections and extracted, forming the pile foundation hole.

[0004] To improve the efficiency of manually excavated pile foundations, automated equipment is needed. However, the installation of power towers in the mountains and forests would cause transportation difficulties. Therefore, an integrated vehicle with an automatic water-grinding drill was designed. However, due to the harsh working environment, the vehicle's battery overheated severely. Summary of the Invention

[0005] The purpose of this application is to provide an integrated vehicle battery water cooling system for manually excavated pile foundations to improve the above-mentioned problems.

[0006] This application provides an integrated battery water-cooling system for manually excavated pile foundation vehicles, which adopts the following technical solution: A water-cooling system for a battery in an integrated vehicle for manually excavated pile foundations is provided, located inside the container of the integrated vehicle. The system includes a water tank installed inside the container; an on-board battery installed inside the container; and a cooling shell covering the on-board battery. The outlet of the water tank is connected to the cooling shell, and the outlet of the cooling shell is connected to a water drill.

[0007] By adopting the above technical solution, the water originally supplied to the water drill is first supplied into the cooling housing to cool the vehicle battery, and then supplied to the water drill, thus achieving reuse, saving resources, and improving resource utilization. At the same time, the cooling housing can protect the vehicle battery and reduce the possibility of damage to the vehicle battery.

[0008] Optionally, the cooling housing includes a main body, a first side plate, and a second side plate. The main body is fitted over the vehicle battery, and the first and second side plates are located on both sides of the vehicle battery and are connected to the main body.

[0009] By adopting the above technical solution, the vehicle battery is fully covered by the main body, the first side plate, and the second side plate, thereby maximizing the cooling and heat dissipation effect.

[0010] Optionally, the main body is composed of two C-shaped cooling bodies joined together, and the two cooling bodies are detachably connected.

[0011] The above technical solution uses two cooling bodies joined together to form the main body, which facilitates the assembly and disassembly of the main body, and thus facilitates maintenance or replacement.

[0012] Optionally, the cooling elements are arranged in an S-shape and form multiple heat dissipation grooves.

[0013] The above technical solution improves the heat dissipation effect by arranging the cooling elements in an S-shape, thereby increasing the contact area between the cooling elements and the vehicle battery.

[0014] Furthermore, the vehicle battery is provided with heat dissipation fins, which are located within a heat dissipation groove. By adopting the above technical solution, the heat dissipation fins can conduct heat out of the vehicle battery more quickly, and the heat dissipation grooves allow the heat dissipation fins to contact the cooling body, further improving the cooling effect.

[0015] Optionally, one end of the cooling body is connected to the top of the first side plate, and the other end is connected to the bottom of the second side plate.

[0016] With the above technical solution, each cooling element is individually connected to the first side plate and the second side plate, which can ensure that the cooling water is filled in the entire cooling element, further improving the cooling effect.

[0017] Optionally, the bottom of the first side plate is connected to the water outlet of the water tank, and the top of the second side plate is connected to the water drill.

[0018] By adopting the above technical solution, the water inlets of the first side plate and the second side plate are both located at the bottom, and the water outlets are both located at the top, so as to ensure that the first side plate and the second side plate are filled with cooling water, thereby further improving the cooling effect.

[0019] Optionally, the cooling body is provided with connecting plates, and the connecting plates of two cooling bodies are connected by bolts.

[0020] By adopting the above technical solution, the two cooling bodies can be detachably connected through the cooperation of connecting plates and bolts.

[0021] Optionally, the first and second side plates at least partially overlap with the cooling body.

[0022] Optionally, both the first and second side plates are provided with limiting blocks on their side walls, and the cooling body is provided with limiting grooves that cooperate with the limiting blocks. By adopting the above technical solution, when assembling the two cooling bodies, the limiting block also cooperates with the limiting groove to fix the first side plate and the second side plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The water originally supplied to the water drill is first supplied into the cooling housing to cool the vehicle battery, and then supplied to the water drill. This achieves reuse, saves resources, and improves resource utilization. At the same time, the cooling housing can protect the vehicle battery and reduce the possibility of damage to the vehicle battery.

[0024] 2. By setting up the main body, the first side plate and the second side plate, the vehicle battery is fully covered, maximizing the cooling effect.

[0025] 3. The main body is formed by splicing two cooling bodies, which facilitates the assembly and disassembly of the main body, and thus facilitates maintenance or replacement.

[0026] 4. By arranging the cooling elements in an S-shape, the contact area between the cooling elements and the vehicle battery is increased, thereby improving the heat dissipation effect.

[0027] 5. The heat dissipation fins dissipate heat from the vehicle battery more quickly, while the heat dissipation grooves allow the fins to contact the cooling body, further improving the cooling effect.

[0028] 6. Each cooling element is individually connected to the first and second side plates, ensuring that cooling water fills the entire cooling element and further improving the cooling effect.

[0029] 7. The water inlets of the first and second side plates are both located at the bottom, and the water outlets are both located at the top, to ensure that the first and second side plates are filled with cooling water and further improve the cooling effect.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Example 1 An integrated device for high-efficiency hole forming of manually excavated piles, referring to Figures 1 to 5 The system includes an integrated vehicle 61, on which is mounted a high-efficiency multi-arm water-cooled drill 83 for manually excavated piles. The integrated vehicle 61 is equipped with a hoisting device, an on-board battery 72, and a power conversion output device. The on-board battery 72 is equipped with a battery water-cooling system for the integrated vehicle's battery for manually excavated piles and a battery management system for the charging and discharging process of construction power. The integrated vehicle 61 transports the high-efficiency multi-arm water-cooled drill 83 to the construction site. The hoisting device is used to hoist the high-efficiency multi-arm water-cooled drill 83 into or out of the hole. During construction, the high-efficiency multi-arm water-cooled drill 83 is powered by the on-board battery 72 and the power conversion output device. The on-board battery 72 undergoes health status assessment through the battery management system for the charging and discharging process of construction power and is cooled by the battery water-cooling system for the integrated vehicle's battery for manually excavated piles. The integrated vehicle 61 is also equipped with a truck-mounted crane 62, so as to lift the multi-arm water-cooled drill 83 for high-efficiency drilling of manually excavated piles from the vehicle or onto the vehicle.

[0051] During construction, the high-efficiency multi-arm water-cooled drill 83 for manually excavated piles is transported to the construction site via an integrated vehicle 61. Then, a hoisting device is used to hoist the high-efficiency multi-arm water-cooled drill 83 into or out of the hole. The high-efficiency multi-arm water-cooled drill 83 is powered by the vehicle-mounted battery 72 and the power conversion output device during construction. The vehicle-mounted battery 72 undergoes health status assessment through the battery management system during the charging and discharging process of the construction power supply, and is cooled by the battery water-cooling system of the integrated vehicle for manually excavated piles. This adapts to various conditions in the construction of manually excavated piles in mountainous areas, improves construction efficiency, and ensures construction quality.

[0052] Reference Figures 2 to 6 The high-efficiency multi-arm water-cooled drilling rig for manually excavated pile foundations is placed inside the manually excavated section of the hole to be excavated. It includes a frame 1, a top support device 2, a leveling base 3, a drilling assembly 4, an angle adjustment device 5, and a distance adjustment mechanism 6. The top support device 2 is hinged to the frame 1 and supports the top of the hole. The leveling base 3 is connected below the frame 1 and is placed at the bottom of the hole; the leveling base 3 can adjust its own levelness. The drilling assembly 4 is used to drill into the bottom of the hole. The angle adjustment device 5 is mounted on the frame 1, and its movable end is connected to the drilling assembly 4, driving the drilling assembly 4 to rotate around the axis of the hole. The movable end of the distance adjustment mechanism 6 is connected to the drilling assembly 4 and is used to adjust the position of the drilling assembly 4 to accommodate holes of different diameters.

[0053] During operation, the hole to be excavated is first dug at the designed location manually or by other means, ensuring a depth of at least 1.5 meters. Then, a high-efficiency multi-arm water-cooled drilling rig for manually excavated piles is placed inside the hole, supported by a top support device 2. The leveling base 3 then fixes the frame 1 within the hole. The leveling base 3 is used to adjust the levelness of the frame 1 to ensure drilling accuracy. Drilling is then performed using the drilling assembly 4, creating a gap between the rock core and the soil. After the drilling assembly 4 is reset, an angle adjustment device rotates it a certain angle, and drilling continues, repeating the process until several rock cores form a ring. The high-efficiency multi-arm water-cooled drilling rig is then lifted, the rock core is broken, and the core is removed, forming a ring-shaped free surface. This automated drilling significantly improves construction efficiency. Simultaneously, the leveling base 3, in conjunction with the top support device 2, ensures overall levelness, thereby guaranteeing drilling accuracy and preventing excessive inclination angles in the hole.

[0054] Specifically, the top support device 2 includes a main rod 21 and support rods 22. The main rod 21 is hinged to the frame 1, and the support rods 22 are connected to the side wall of the main rod 21. Multiple support rods 22 are arranged along the circumference of the main rod 21, and the end of the support rod 22 away from the main rod 21 can be adjusted relative to the main rod 21. The support rods 22 can be made of jacks, electric cylinders, or linear motors. By moving the ends of the multiple support rods 22 away from the main rod 21 in opposite directions, the main rod 21 is fixed relative to the side wall of the hole to be excavated. At the same time, the main rod 21 is hinged to the frame 1, so that after the leveling base 3 is adjusted, the support rods 22 and the main rod 21 are not affected.

[0055] The leveling base 3 is threaded with multiple bolt legs 31, which are arranged in a circumferential array along the leveling base 3. A gyroscope inclinometer 32 and an electric torque wrench 33 are also mounted on the leveling base 3. The number of electric torque wrenches 33 is the same as the number of bolt legs 31, and they correspond one-to-one. The movable end of the electric torque wrench 33 is connected to the corresponding bolt leg 31 to drive the corresponding bolt leg 31 to rotate. The gyroscope inclinometer 32 is electrically connected to the electric torque wrench 33. The gyroscope inclinometer 32 detects the angle of the leveling base 3, then drives the corresponding electric torque wrench 33 to start, causing the corresponding bolt leg 31 to rotate, thereby adjusting the levelness of the leveling base 3 and, consequently, the levelness of the frame 1. A travel motor 34 is mounted on the frame 1, and the movable end of the travel motor 34 is connected to the electric torque wrench 33 to drive the electric torque wrench 33 to move vertically.

[0056] The angle adjustment device 5 includes a first rotating component 51, a drive shaft 52, and a turntable 53. The first rotating component 51 is mounted on the frame 1. The movable end of the first rotating component 51 is connected to the drive shaft 52, the drive shaft 52 is connected to the turntable 53, and the turntable 53 is connected to the distance adjustment mechanism 6. Two sets of distance adjustment mechanisms 6 are provided: one set located below and connected to the turntable 53; the other set located above and connected to the frame 1. The end of the distance adjustment mechanism 6 away from the frame 1 is connected to the drilling assembly 4 to adjust the distance between the drilling assembly 4 and the frame 1. The distance adjustment mechanism 6 can be a snap-fit ​​adjustment device, or it can be a linear motor or electric cylinder, as long as it can adjust the distance between the drilling assembly 4 and the frame 1.

[0057] It should be noted that there are multiple drilling components 4, and multiple drilling components 4 are arranged in a circumferential array along the leveling base 3, with multiple drilling components 4 located on the outside of the leveling base 3.

[0058] Reference Figures 7 to 9 The integrated battery water-cooling system for the manually excavated pile foundation vehicle is located inside the container 7 of the integrated vehicle. It includes a water tank 71, an onboard battery 72, and a cooling shell 73. Both the water tank 71 and the onboard battery 72 are installed inside the container 7. The cooling shell 73 encloses the onboard battery 72. The outlet of the water tank 71 is connected to the cooling shell 73, and the outlet of the cooling shell 73 is connected to the water drill. Water originally intended for the water drill is first supplied to the cooling shell 73 to cool the onboard battery 72 before being supplied to the water drill, achieving reuse, saving resources, and improving resource utilization. Simultaneously, the cooling shell 73 protects the onboard battery 72, reducing the possibility of damage.

[0059] Specifically, the cooling housing 73 includes a main body, a first side plate 731, and a second side plate 732. The main body is fitted over the vehicle battery 72, and the first side plate 731 and the second side plate 732 are located on both sides of the vehicle battery 72 and are connected to the main body. The main body, the first side plate 731, and the second side plate 732 completely cover the vehicle battery 72, maximizing the cooling effect. The main body is composed of two C-shaped cooling elements 733 joined together, and the two cooling elements 733 are detachably connected. The two cooling elements 733 joined together form the main body, facilitating its assembly and disassembly, and thus facilitating maintenance or replacement.

[0060] More specifically, the cooling elements 733 are arranged in an S-shape, forming multiple heat dissipation slots 734. The S-shaped arrangement of the cooling elements 733 increases the contact area between the cooling elements 733 and the vehicle battery 72, thereby improving heat dissipation. The vehicle battery 72 is equipped with heat dissipation fins 721, which are located within the heat dissipation slots 734. The heat dissipation fins 721 more quickly dissipate heat from inside the vehicle battery 72, and the heat dissipation slots 734 allow the heat dissipation fins 721 to contact the cooling elements 733, further enhancing the cooling effect.

[0061] One end of the cooling element 733 is connected to the top of the first side plate 731, and the other end is connected to the bottom of the second side plate 732. Each cooling element 733 is individually connected to the first side plate 731 and the second side plate 732, which ensures that cooling water fills the entire cooling element 733, further improving the cooling effect.

[0062] The bottom of the first side plate 731 is connected to the outlet of the water tank 71, and the top of the second side plate 732 is connected to the water drill. The inlets of the first side plate 731 and the second side plate 732 are both located at the bottom, and the outlets are both located at the top, to ensure that the first side plate 731 and the second side plate 732 are filled with cooling water, thereby further improving the cooling effect.

[0063] In addition, the cooling body 733 is provided with a connecting piece 735, and the two cooling bodies 733 are connected by bolts. The two cooling bodies 733 are detachably connected by the cooperation of the connecting piece 735 and the bolts.

[0064] It should be noted that the first side plate 731 and the second side plate 732 at least partially overlap with the cooling body 733. Each of the side walls of the first side plate 731 and the second side plate 732 is provided with a limiting block 736, and the cooling body 733 is provided with a limiting groove 737 that mates with the limiting block 736. When assembling the two cooling bodies 733, the limiting block 736 also mates with the limiting groove 737 to fix the first side plate 731 and the second side plate 732. The limiting block 736 has an arc-shaped cross-section.

[0065] This design first supplies water originally intended for the water drill into the cooling housing 73 to cool the vehicle battery 72 before supplying it to the drill, thus achieving reuse, saving resources, and improving resource utilization. Simultaneously, the cooling housing 73 protects the vehicle battery 72, reducing the possibility of damage. The main body, first side plate 731, and second side plate 732 completely cover the vehicle battery 72, maximizing cooling efficiency.

[0066] The main body is formed by splicing two cooling elements 733 together, which facilitates the assembly and disassembly of the main body, thereby facilitating maintenance or replacement. The S-shaped arrangement of the cooling elements 733 increases the contact area between the cooling elements 733 and the vehicle battery 72, thereby improving heat dissipation.

[0067] The heat dissipation fins 721 dissipate heat from the vehicle battery 72 more quickly, while the heat dissipation channels 734 allow the fins 721 to contact the cooling body 733, further enhancing the cooling effect. Each cooling body 733 is individually connected to the first side plate 731 and the second side plate 732, ensuring that the entire cooling body 733 is filled with coolant, further improving the cooling effect. The water inlets of the first side plate 731 and the second side plate 732 are both located at the bottom, and the water outlets are both located at the top, ensuring that the first side plate 731 and the second side plate 732 are filled with coolant, further enhancing the cooling effect.

[0068] Reference Figures 10 to 13 The hoisting device can be used to hoist high-efficiency multi-arm water-cooled drills for manually excavated pile foundations, and also to hoist core samples generated by drilling components. The hoisting device includes a hoisting platform 9, a hoisting device 95, a suspended basket 96, a gas detector 97, and an alarm device 98. The hoisting platform 9 is installed on the ground; the hoisting device 95 is mounted on the hoisting platform 9; the suspended basket 96 is connected to the movable end of the hoisting device 95 and is used to place it into the pile foundation hole; the gas detector 97 is mounted on the suspended basket 96 and is used to detect toxic gases and the oxygen content in the air; the gas detector 97 is electrically connected to the hoisting device 95; the alarm device 98 is mounted on the hoisting platform 9 and is electrically connected to the gas detector 97. During operation, the suspended basket 96 is hoisted by the hoisting device 95 to facilitate the extraction of the rock core from the pile foundation hole. Simultaneously, the gas detector 97 detects toxic gases in the pile foundation hole. If the toxic gas content exceeds the standard, the hoisting device 95 lifts both the suspended basket 96 and the workers to prevent danger.

[0069] Specifically, the bottom of the lifting platform 9 is provided with a concrete base 91, which is located in the ground. The concrete base 91 supports the lifting platform 9, making the lifting platform 9 more secure and improving its stability.

[0070] A fall arrestor 92 is connected to the hoisting platform 9, with its movable end for workers to wear. The fall arrestor 92 provides secondary protection for workers, preventing the suspended platform 96 from suddenly falling and causing danger. The fall arrestor 92 is located on one side of the hoisting device 95, and the worker stands on the suspended platform 96, positioned below the gap between two adjacent booms 961. Positioning the fall arrestor 92 on one side of the hoisting device 95 reduces the possibility of interference between the fall arrestor 92 and the hoisting device 95, while positioning the worker below the gap between the two booms 961 reduces the possibility of collision between the booms 961 and the worker if the suspended platform 96 falls.

[0071] The suspended platform 96 includes a frame 961, lifting rods 961, and lifting rings 963. Multiple lifting rods 961 are hinged to the frame 961, and adjacent lifting rods 961 are fixedly connected to a lifting ring 963. The lifting ring 963 is used to connect to the movable end of the lifting device 95. The hinged connection between the lifting rods 961 and the frame 961 facilitates opening the platform 96 when loading and unloading rock cores, improving loading and unloading efficiency. The side wall of the frame 961 is provided with anti-collision buffer pads 964 to protect the suspended platform 96 and prevent the suspended platform 96 from colliding with the side wall of the pile foundation hole and causing damage.

[0072] The lifting device 95 is movable on the lifting platform 9, one end of which extends above the unloading area 94. After lifting the basket 96, the lifting device 95 moves on the lifting platform 9 above the unloading area 94 for unloading.

[0073] More specifically, the concrete base 91 includes a concrete block 911, a pre-embedded connector 912, and a supporting base plate 913. The concrete block 911 is poured into the ground. One end of the pre-embedded connector 912 is embedded in the concrete block 911, and the other end is fixedly connected to the supporting base plate 913. The supporting base plate 913 is fixedly connected to the lifting platform 9, and reinforcing ribs 914 are welded between the supporting base plate 913 and the lifting platform 9. By connecting the concrete block 911 to the pre-embedded connector 912, and then connecting the pre-embedded connector 912 to the supporting base plate 913, the lifting platform 9 is firmly fixed to the ground.

[0074] A counterweight 93 is provided on the side of the lifting platform 9 away from the unloading area 94. The counterweight 93 is used to balance the lifting platform 9, further improving the stability of the lifting platform 9.

[0075] The bottom of the lifting platform 9 is also equipped with a support device, which has a supported state and a released state. When the support device is in the supported state, the movable end of the support device extends into the pile hole and supports the top of the pile hole. When the support device is in the released state, the movable end of the support device is detached from the pile hole and is located on the outside above the pile hole. By setting up the support device, the top of the pile hole is supported when the lifting device 95 is working, thereby reducing the possibility of collapse. When the basket 96 is not working, the support device can also be retracted to avoid affecting other operations.

[0076] The battery management system for the charging and discharging process of construction power includes an on-board battery, a start-up battery, and a controller. There are at least two start-up batteries. The output terminal of the start-up battery is electrically connected to the discharge circuit, and the input terminal of the start-up battery is electrically connected to the charging circuit. The battery discharge circuit is electrically connected to the starting unit of the on-board battery, and the battery controller is electrically connected to the power management system of the start-up battery to obtain the remaining power data.

[0077] The battery management system also includes a charging device, which can be a photovoltaic power generation device or an external charging circuit. When the vehicle battery starts, the battery controller selects the battery with the highest remaining charge to discharge, thus powering the vehicle battery for startup. It also controls the charging of the remaining chargeable batteries based on their remaining charge levels. By assigning multiple chargeable batteries to different vehicle battery configurations, the system ensures fast response times and extends the battery's lifespan.

[0078] A supercapacitor is installed in the battery discharge circuit to absorb the current spike that occurs when the battery starts discharging.

[0079] Reference Figure 14 A battery SOH estimation method, applied to the battery management system for the charging and discharging process of the above-mentioned construction power supply, includes the following steps: S1. Establish a lithium-ion battery cycle life test platform and obtain battery data sets under four different operating conditions. The battery data sets were collected from four aging tests, all using constant current / constant voltage and constant current discharge methods. In constant current / constant voltage mode, the battery was charged to the upper cutoff voltage using a specified constant current, and then charged again using the upper cutoff voltage until the current dropped below 0.05C. In constant current discharge mode, the battery was discharged at a specified constant current to a lower cutoff voltage, at which point the cycle life test stopped, until the capacity dropped below 80% of the initial capacity. The operating condition settings for the lithium-ion batteries in the aging test conditions are detailed below. Figure 15 L1 to L16 are the names of different lithium battery packs. The lithium batteries are commercial pouch-type lithium-ion batteries with a capacity of 12Ah.

[0080] S2. Analyze and process the battery dataset to construct a feature library, specifically: S2.1 Analyze the battery dataset from the perspective of battery attributes and construct attribute features. Attribute features include voltage, current, capacity, energy, IC curve, capacity change, energy change, average voltage, ohmic internal resistance, and polarization resistance. Among these, ohmic resistance... polarization resistance ; This represents the change in current. This represents the voltage difference within 1 second. This indicates the voltage change within 1 second to 20 seconds.

[0081] S2.2 Analyze attribute features from the perspective of data range and construct data range features. Based on the charging mode, the attribute features are divided into three parts for feature extraction: CC stage, CV stage, and CC-CV stage, with each charging segment representing a battery charging data curve.

[0082] S2.3. Analyze the data range characteristics from a mathematical and statistical perspective to construct mathematical features. Convert each battery charging data curve into eight statistical values: quantiles, maximum value, minimum value, mean, variance, kurtosis, skewness, and slope, to capture the shape and positional evolution of each cycle curve; quantiles reflect evolution by sampling the values ​​at each quantile position; the mean measures the average level of each curve within a fixed range; variance is used to evaluate the non-uniformity of the data stream distribution, with a larger variance indicating a more non-uniform distribution; skewness and kurtosis characterize the shape of each curve; and slope represents the lateral polarization of the battery.

[0083] S2.4. The attribute features, data range features, and mathematical features are combined to form a feature library. Based on the charging mode, each of the 10 attribute features is divided into 3 charging segments, and each charging segment is converted into 8 statistical values. Through combined statistical methods, a comprehensive feature library with 240 mechanical statistical fusion features is generated for the battery under study.

[0084] S3. Use the highest relevance search method to select the most relevant features from the feature library to obtain the model input features. S3 includes the following steps: S3.1 Evaluate the nonlinear correlation between features in the feature library and SOH, and select features with a correlation greater than the first set threshold; S3.2 Decentralize the selected features and make the mean of the features 0; S3.3 Calculate the covariance matrix of the decentralized result; S3.4. Eigenvalues ​​and eigenvectors are obtained by eigenvalue decomposition and singular value decomposition of the covariance matrix to determine the variance contribution rate and cumulative variance contribution rate; S3.5 Select features whose cumulative variance contribution rate is greater than the second set threshold, and calculate the splitting gain of these features using the maximum gradient boosting method; S3.6. Average the splitting gain of the features to obtain the importance score of each feature; S3.7 Select the features with the highest importance scores as the input features of the model.

[0085] S4. Feed the model input features into a dual-channel interpretability network to obtain the SOH estimation result. The dual-channel interpretability network includes a global channel, local channels, an interactive attention mechanism, and a fully connected layer. S4 includes the following steps: S4.1. Perform min-max normalization on the input features of the model, and then feed them into the dual-channel interpretability network; S4.2 The outputs of the max-min normalization are processed by the global channel and the local channel respectively and then sent to the interactive attention mechanism. S4.3 The interactive attention mechanism uses the output of the global channel as the input of its own query operation to locate key temporal segments in the local channel that are related to the overall health status, guided by the global degradation trend; and uses the output of the local channel as its own key and value input to map the local dynamic response to the global degradation framework; and generates an attention weight matrix through the Softmax function to quantify the importance of global and local features. S4.4 The output of the interactive attention mechanism is passed through a fully connected layer to obtain the SOH estimation result.

[0086] It should be noted that the formula for the interactive attention mechanism is as follows:

[0087] in, , and These represent linear transformations of the query, key, and value, respectively. Indicates the transpose of the key. The dimension representing the key. This represents the Softmax activation function.

[0088] Furthermore, the global channel includes a hidden layer, a max-min normalization layer, a B-spline activation function, and a regularization layer. The input features are 4-dimensional data, and the hidden layer has 9 nodes. The input features of the global channel are subjected to max-min normalization and scaled to a fixed range [-1, 1]. The B-spline function is used as the activation function, and the model structure is optimized through sparse regularization and pruning to obtain the output of the global channel.

[0089] The local channel includes a sliding window, multi-scale convolutional layers, ReLU activation function, and global pooling layer. The sliding window segments the input features into fixed-length subsequences to capture local temporal patterns. Multi-scale convolutional layers are used to extract local patterns at different time scales in parallel and calculate the weighted sum of local regions. The ReLU activation function is used to zero out negative values ​​and retain positive values ​​to focus on positive value regions and filter out local features strongly correlated with battery aging. Global pooling operation compresses the content extracted by multi-scale convolution to the mean to preserve global temporal patterns.

[0090] It should be noted that the battery in this solution can be a lithium battery.

[0091] Working principle: By analyzing and processing battery datasets under four different operating conditions, it can solve the problem of effective feature input for batteries of different types, operating conditions and materials. It obtains a rich feature library by analyzing battery datasets from multiple perspectives, and then achieves automatic transparent feature selection through the highest correlation search method, effectively reducing redundant data input, extracting highly correlated features, and solving the problem of recent trends and historical dependencies in battery data, providing new insights into the field of SOH estimation for ion batteries.

[0092] Reference Figure 16 The power conversion output device includes an output shaft 8, a gear set 81, and a generator 82. One end of the output shaft 8 is connected to the vehicle's power system, and the other end is connected to the gear set 81. The output end of the gear set 81 is connected to the generator 82. The generator 82 is electrically connected to the water drill 83. After the integrated vehicle 61 shifts gears, the vehicle's power system transmits power to the output shaft 8. The output shaft 8 drives the generator 82 to generate electricity through the gear set 81, and supplies power to the water drill 83.

[0093] By combining the vehicle's power system with the generator 82, the vehicle's power can be used to drive the generator 82 to generate electricity, which in turn supplies power to the water drill 83. This solves the problem that the existing water drill 83 has a single power supply mode and cannot meet the construction needs, thus improving construction efficiency. At the same time, it can cope with emergencies such as damage to the vehicle battery 72 or depletion of power.

[0094] The vehicle-mounted battery 72 is electrically connected to the water drill 83 and the generator 82. The vehicle-mounted battery 72 is electrically connected to both the water drill 83 and the generator 82, which allows it to store the energy generated by the generator 82 and then provide power to the water drill 83, further improving the flexibility of power supply.

[0095] A construction method, based on the aforementioned integrated equipment for efficient hole forming of manually excavated bored piles, includes the following steps: S1, the integrated vehicle 61 transports the high-efficiency drilling multi-arm water-cooled drill 83 for manually excavated piles to the construction site; S2, Assembly of a high-efficiency multi-arm water-cooled drill for manually excavated piles; S3. Excavate the hole to be excavated at the designed location, ensuring that the depth of the hole is not less than 1.5 meters; S4. Place the high-efficiency drilling multi-arm water-cooled drill 83 for manually excavated piles into the hole to be excavated, and support the top of the hole to be excavated through the top support device 2, and then fix the frame 1 into the hole to be excavated in conjunction with the leveling base 3. S5. Adjust the level of the frame 1 by adjusting the leveling base 3 to ensure drilling accuracy; S6. Drilling is carried out through the drilling component 4, so that there is a gap between the rock core and the soil inside the drilling component 4; S7. After the drilling assembly 4 is reset, the angle adjustment device drives the drilling assembly 4 to rotate a certain angle and then the drilling assembly 4 continues to drill. S8. Repeat S6 and S7 until the core forms a ring. S9. The 83-arm water-cooled drill for high-efficiency drilling of manually excavated piles is lifted up, and then the rock core is broken and removed to form a ring-shaped free surface.

[0096] It should be noted that in steps S6 and S7, the high-efficiency drilling multi-arm water-cooled drill 83 for manually excavated piles is powered by the vehicle battery 72 and the power conversion output device. The vehicle battery 72 provides power first. When the vehicle battery 72 is low on power, the power conversion output device provides power. When the high-efficiency drilling multi-arm water-cooled drill 83 for manually excavated piles is not working, the power conversion output device supplies power to the vehicle battery 72.
