Description

Technical Field

[0001] The present invention relates to the technical field of transmission lines, and specifically to a standard section and storage method of a repair tower set for transmission lines. Background Art

[0002] With the increasing scale of cross-regional power grids, due to the complex meteorological, geological, and topographical conditions of the line corridors, disasters such as wind and ice seriously threaten the safe operation of the lines. In addition, the line transmission capacity is large, and once a power outage occurs, the economic and social impacts are greater, which also puts higher requirements on the rapid restoration of power supply. After a tower collapse incident, it is an important part of the power grid's disaster prevention and mitigation work to urgently repair the damaged line, restore power supply as soon as possible, and reduce economic losses and social impacts. The repair of transmission towers generally formulates a repair plan according to the damage of the foundation. When the foundation is intact and suitable for continuing to erect the tower, the original tower position is generally used for tower erection repair; when the foundation is damaged or the repair time cannot meet the demand for timely power supply restoration, a repair tower is used to temporarily restore power supply first, and at the same time, tower erection repair is carried out at a suitable position. A repair tower is a type of tower that uses a guy wire form, does not require foundation pouring, can be quickly erected, and can quickly restore power supply. It belongs to a temporary emergency facility.

[0003] The overhead transmission line repair tower is usually in the form of a guyed tower, including various components such as a tower body section, a tower column base, a guy wire foundation, guy wires, connecting fittings, a composite insulation cross arm, a guy wire connecting plate, hanging accessories, bolts, and construction tools. There are many components, many specifications, large differences in size, and different materials. As emergency repair materials, the standard sections of repair towers have the following characteristics: First, the usage frequency is low and long-term storage is required; second, after use, they need to be recycled and reused, and require repeated loading, unloading, handling, and assembly; third, time is precious, and the in-transit transportation time of the standard sections should be minimized. Currently, the existing standard sections of repair towers in power grid companies usually adopt forms such as warehouse storage and outdoor storage, and there are problems such as poor management, missing parts, and exposure to the wind and sun. A small number use container storage, but usually there is no dedicated functional zoning, the space utilization rate of the container is not high, the items are placed in a mess, and there is still a gap from the actual demand.

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] Please refer to Figure 1 , a standard section of a transmission line emergency repair tower set of the present invention includes a tower sleeve. The upper and lower ends of the tower sleeve are respectively provided with an upper standard section 1 and a lower standard section 2. The opening of the upper standard section 1 of the tower sleeve is small, and the opening of the lower standard section 2 is large. The opening of the upper standard section 1 in the tower sleeve is smaller than the opening of the lower standard section 2. The upper standard section 1 and the lower standard section 2 are connected by a transition section. Guide angle steels and nylon pulleys are arranged inside the upper standard section 1 and the lower standard section 2 for the upper standard section 1 to be sleeved into the lower standard section 2. Steps 4 are built in the sides of the upper standard section 1 and the lower standard section 2 and do not protrude from the outer contour.

[0051] Preferably, the upper standard section 1 has a small opening and the lower standard section 2 has a large opening, which enables the upper standard section 1 to be easily sleeved into the lower standard section 2, simplifies the assembly process, and reduces the on-site operation time.

[0052] Preferably, guide angle steels and nylon pulleys are arranged inside the upper standard section 1 and the lower standard section 2, further simplifying the sleeving process, reducing the operation difficulty, and improving the loading and unloading efficiency.

[0053] Preferably, the side built-in step 4 is designed not to protrude from the outer contour, reducing the risk of collision with other components during transportation and storage, and improving the safety.

[0054] In the specific embodiment of the present invention, the transition section 3 is adjustable to adapt to the requirements of different sizes and shapes, enhancing the versatility and flexibility of the standard section and reducing the need for special components.

[0055] In the specific embodiment of the present invention, the transition section 3 is made of lightweight and high-strength materials such as aluminum alloy or high-strength steel, reducing the overall weight, facilitating transportation and loading and unloading, and ensuring the structural stability and safety at the same time.

[0056] The crossbeam standard section is sleeved into the upper standard section 1 to form a three-layer sleeve, realizing multi-layer sleeve storage, maximizing the use of storage space, and improving the transportation efficiency.

[0057] At the same time, the present invention designs modular partitions inside the container, and different types of standard sections or fittings are stored in each area, facilitating quick search and use:

[0058] Upper standard section area: Store standard sections with smaller openings.

[0059] Lower standard section area: Store standard sections with larger openings.

[0060] Crossbeam and transition section area: Store crossbeams and the transition section 3.

[0061] Fitting area: Store small fittings such as bolts, fasteners, pulleys, and guide rails.

[0062] The upper standard section 1 is sleeved into the lower standard section 2, and the crossbeam is sleeved into the upper standard section 1, realizing multi-layer sleeve storage, maximizing the use of the container space, and reducing the transportation cost.

[0063] Clear signs are set in each storage area, indicating the component name, quantity, and sleeving method, facilitating quick identification and operation, and reducing errors and delays.

[0064] Record the status, location, and maintenance history of each standard section, update the inventory information in real time, ensure that the standard section is available at any time, and avoid the risk of component shortage or expiration.

[0065] The current status of each standard section, i.e., in stock, in transit, and in use, is displayed in real time, facilitating scheduling and management and improving the emergency repair response speed.

[0066] The usage time, usage location, and user information of the standard section are recorded, facilitating traceability and analysis and optimizing the maintenance and management processes.

[0067] Based on the usage frequency and failure rate of the standard section, the inventory strategy is dynamically adjusted to reduce redundant inventory, improve inventory turnover rate, and lower storage costs.

[0068] By analyzing the reliability of the standard section through maintenance history data, the maintenance requirements are predicted in advance, the failure downtime of the standard section is reduced, and the smooth progress of emergency repair work is ensured. The standardized design and internal guide rails and pulleys simplify the assembly process and reduce on-site operation time. The lightweight materials and multi-layered set storage maximize the use of transportation space and reduce transportation costs. The real-time status tracking and maintenance cycle calculation ensure the reliability of the standard section during emergency repair and reduce the failure downtime. The dynamic inventory strategy and usage frequency analysis reduce redundant inventory, improve inventory turnover rate, and lower storage costs. The digital management and clear identification system simplify the inventory and maintenance processes and improve management accuracy.

[0069] In another embodiment of the present invention, a storage method for standard sections of a transmission line emergency repair tower set is provided. The storage method includes the following steps:

[0070] S1, Digital management: Record the status, location, and maintenance history of each standard section, update the inventory information in real time, and avoid missing or expired components; Calculate the inventory turnover rate based on the status of each standard section in the inventory information;

[0071] S2, Status tracking: Display the current status of each standard section in real time. The current status includes in stock, in transit, and in use; Obtain the usage frequency of each standard section based on the usage time, usage location, and user information of each standard section, and obtain the failure rate of the standard section based on the usage frequency of the standard section; Usage record: Record the usage time, usage location, and user information of the standard section;

[0072] S3, Inventory optimization: Adjust the inventory strategy of the standard section according to the usage frequency, reliability, and inventory turnover rate of each standard section, adjust the inventory strategy, optimize the inventory quantity, reduce redundant inventory, and improve the inventory turnover rate.

[0073] Preferably, the state probability distribution of each standard section is calculated according to the state of each standard section as:

[0074]

[0075] Where: P(S i)The probability that the standard segment is in state S i ; N total is the total number of standard segments; N i represents the number of standard segments in state S i .

[0076] Directly calculate the probability through the total number of standard segments N total and the number of standard segments N i in a certain state S i . No complex mathematical models or algorithms are required. Just count the total number of standard segments and the number of each state to quickly obtain the result. This method dynamically updates the probability distribution according to the real-time state of the standard segments in the library, in transit, and in use. Each time the state of the standard segment changes, just update the corresponding N i value to recalculate the probability.

[0077] Preferably, in order to avoid the expiration of the standard segment, calculate the maintenance period of the standard segment and analyze the reliability of the standard segment through maintenance history data:

[0078]

[0079] where: Mean MTBF is the average maintenance period; n is the number of maintenance times; T i represents the time interval of the i-th maintenance;

[0080] Calculation of the maintenance risk index:

[0081]

[0082] where: Risk Index(t) is the maintenance risk index at time t; Last Maintenance is the time of the last maintenance.

[0083] By calculating the maintenance risk index in advance, arrange maintenance before the risk of the standard segment reaches the critical value to avoid the standard segment from shutting down due to failure and reduce the risk of emergency repair work.

[0084] Through accurate calculation of the average maintenance period, reasonably arrange the maintenance time to avoid the standard segment from becoming invalid or expired due to long-term lack of maintenance, and ensure that the standard segment is always in the best state.

[0085] By calculating the maintenance period and risk index, reasonably arrange limited maintenance resources such as personnel, tools, and spare parts to avoid waste of resources.

[0086] If the risk index of a certain standard segment is high, give priority to arranging maintenance to ensure the efficient operation of key standard segments and reduce resource idleness at the same time.

[0087] By analyzing the cycle and risk index maintained through long-term records, the reliability trend of the standard section is analyzed, such as whether the standard section is gradually aging or operating stably, providing a basis for formulating long-term maintenance strategies.

[0088] Compare the maintenance cycles and risk indices of different standard sections or different time periods to identify the standard sections with poor performance or weak management links, and further optimize the maintenance strategy.

[0089] Through timely maintenance, the probability of the standard section being shut down due to faults is reduced, ensuring the efficient progress of emergency repair work.

[0090] If the risk index of a certain standard section is too high, give an early warning to ensure that the standard section at the emergency repair site is always in an available state.

[0091] By accurately calculating the maintenance cycle, unnecessary frequent maintenance is avoided, reducing the maintenance cost.

[0092] Through preventive maintenance, the downtime of the standard section due to faults is reduced, and the downtime loss during emergency repair work is reduced.

[0093] Preferably, calculate the inventory turnover rate according to the current state, and the inventory turnover rate is calculated as:

[0094]

[0095] Where: Inventory Turnover is the inventory turnover rate; Average_Inventory_Value is the average inventory value, and Total_Cost_of_Goods_Sold is the total inventory value.

[0096] Intuitively quantify inventory efficiency: The inventory turnover rate can directly reflect the inventory flow speed of an enterprise within a certain period of time, providing a quantitative indicator for managers to clearly understand the effect of inventory management. Through this indicator, an enterprise can quickly evaluate the efficiency of its own inventory operation.

[0097] The present invention can realize dynamic monitoring of the inventory status, reflect the changes in the inventory in real time, help the enterprise monitor the inventory status, timely discover potential problems, and avoid inventory overstock or shortage.

[0098] The present invention can avoid inventory backlog. A high inventory turnover rate means a fast inventory turnover speed, effectively avoiding inventory backlog and reducing unnecessary warehousing costs. Through this indicator, an enterprise can reasonably control the inventory level and avoid the waste of funds and warehousing space.

[0099] The present invention can reduce the risk of inventory backlog. The calculation of inventory turnover rate helps enterprises to promptly identify slow-moving products or backlogged inventory, and thus take corresponding measures, such as promotions or adjusting the procurement plan, to reduce the risks brought by inventory backlog.

[0100] Preferably, during the turnover process, the transportation cost of the standard section also needs to be considered. Therefore, it is necessary to calculate the in-transit time:

[0101]

[0102] where: Transport Time is the in-transit time; v is the transportation speed;

[0103] and calculate the expected arrival time in the in-transit state:

[0104] ETA = t start + Transport Time

[0105] where: ETA is the expected arrival time.

[0106] By calculating the in-transit time and the expected arrival time, enterprises can accurately predict the arrival time of goods. The method is based on the actual distance and transportation speed, and can provide a relatively accurate time estimate, helping enterprises to better arrange production and delivery plans. The accurate expected arrival time improves customer satisfaction. Customers can understand the arrival time of goods in advance, and thus reasonably arrange the receiving and using plans, which not only reduces the waiting time of customers, but also enhances the trust and loyalty of customers.

[0107] Through accurate estimation of the in-transit time, enterprises can better allocate resources. For example, arrange warehouse personnel and standard sections before the expected arrival time to ensure the rapid unloading and warehousing of goods, and improve the overall operation efficiency.

[0108] The accurate calculation of the in-transit time and the expected arrival time helps to reduce transportation delays and avoid additional costs caused by delays, such as warehousing costs and customer fines. This not only reduces the operating costs, but also enhances the profitability of enterprises.

[0109] This method provides a transparent estimate of the in-transit time, enabling enterprises in the upstream and downstream of the supply chain to better cooperate. Suppliers and customers share the information of the expected arrival time and jointly arrange production and distribution plans, improving the efficiency and reliability of the entire supply chain.

[0110] By calculating the in-transit time and the expected arrival time in real time, enterprises can quickly respond to emergencies during the transportation process, such as traffic congestion or weather changes. This helps to timely adjust the transportation plan and ensure the goods arrive on time.

[0111] Accurate in-transit transportation time and estimated arrival time data provide strong support for the enterprise's decision-making. The management formulates more reasonable logistics strategies based on these data, improving the scientificity and rationality of the overall operation.

[0112] Preferably, real-time updating of inventory information requires tracking the status of each standard segment. The status tracking is calculated through status updates, and the status update calculation is:

[0113] N i (t) = N i (t - 1)+ΔN i

[0114] Where: N i (t) is the number of standard segments in state S at time t i ; ΔN i is the change in the number of standard segments in state S between time intervals t - 1 and t i ;

[0115] When the standard segment returns from the in-transit or used state to the in-stock state, update the number of in-stock standard segments, and its calculation is:

[0116] N 在库 (t) = N 在库 (t - 1)+ΔN 在库

[0117] Where: ΔN 在库 is the number of standard segments returned to the in-stock state between time intervals (t - 1) and t;

[0118] When the standard segment is issued from the in-stock state or returns from the used state to the in-stock state, update the number of in-transit standard segments, and its calculation is:

[0119] N 在途 (t) = N 在途 (t - 1)+ΔN 在途

[0120] Where: ΔN 在途 is the number of standard segments entering the in-transit state between time intervals t - 1 and t;

[0121] When the standard segment arrives at the usage location from the in-stock state or in-transit state, update the number of used standard segments, and its calculation is:

[0122] N 已使用 (t) = N 已使用 (t - 1)+ΔN 已使用

[0123] Where: ΔN 已使用is the number of standard segments that enter the used state between time intervals t-1 and t.

[0124] In the specific embodiment of the present application, the probability of each state is calculated in real time as:

[0125]

[0126] where: P(S i (t)) is the probability that the standard segment is in state S at time t; N i ; N total (t) is the total number of standard segments at time t.

[0127] In the specific embodiment of the present application, the usage time of the standard segment is calculated as:

[0128] T usage = t end - t start

[0129] where: T usage is the usage time of the standard segment; t end is the time when the standard segment ends its use;

[0130] The usage location of the standard segment is calculated as:

[0131] Location = (x, y)

[0132] where: Location is the usage location of the standard segment; y is the latitude coordinate of the location; x represents the longitude coordinate of the geographical location.

[0133] In the specific embodiment of the present application, the usage frequency is calculated as:

[0134]

[0135] where: F is the usage frequency of the standard segment, times / time; T window is the length of the statistical time window, N total represents the total number of times the standard segment is used within the given time window;

[0136] The failure rate is calculated as:

[0137]

[0138] where: R is the failure rate of the standard segment, number of failures / times; N total is the total number of times the standard segment is used within the time window; N failure represents the total number of failures of the standard segment within the given time window.

[0139] By counting the usage times and failure times of standard segments within a given time window, this method can objectively reflect the operating conditions and reliability of standard segments. The specific values of the usage frequency and failure rate provide a quantitative basis for the performance evaluation of standard segments, helping management clearly understand the actual performance of standard segments.

[0140] The calculation of the usage frequency can help enterprises identify standard segments with high usage frequency, thus ensuring that these standard segments are always in good condition and avoiding failures caused by high-frequency usage. The calculation of the failure rate can help enterprises discover standard segments prone to failures, and then take targeted measures, such as strengthening maintenance or replacing key components, to reduce the failure risk.

[0141] By statistically analyzing the usage frequency and failure rate of standard segments, enterprises can allocate resources more reasonably. For example, prioritize the maintenance of standard segments with high usage frequency to ensure their stable operation; focus on monitoring and improving standard segments with high failure rates to reduce their impact on production and operation.

[0142] The data of usage frequency and failure rate provide a basis for enterprises to predict the future performance of standard segments. By analyzing these data, enterprises can predict the maintenance requirements, failure probabilities, and life cycles of standard segments, so as to formulate maintenance plans in advance and avoid the impact of sudden failures on production and operation.

[0143] Specific numerical indicators make decision-making more scientific and accurate. Management formulates reasonable procurement, maintenance, and elimination strategies for standard segments based on the calculation results of usage frequency and failure rate to ensure the long-term benefits of standard segment management.

[0144] By monitoring and analyzing the failure rate, enterprises can identify potential problems in the operation of standard segments, take preventive measures to reduce the failure incidence, and thus improve the reliability of standard segments and the overall operation efficiency.

[0145] The calculation methods of usage frequency and failure rate encourage enterprises to continuously monitor and analyze the usage and failure conditions of standard segments, discover improvement opportunities and take corresponding measures to achieve the continuous optimization of standard segments and the improvement of operation efficiency.

[0146] Preferably, adjust the inventory strategy of standard segments according to the usage frequency, reliability, and inventory turnover rate of each standard segment. The specific steps for optimizing the inventory quantity include the following:

[0147]

[0148] Where: Q new is the adjusted inventory quantity; F is the usage frequency of the standard segment; R is the failure rate of the standard segment; α, β, γ are weight coefficients, representing the weights of usage frequency, failure rate, and inventory turnover rate respectively.

[0149] By comprehensively considering the usage frequency, failure rate, and inventory turnover rate of standard segments, the inventory can be adjusted more reasonably. This helps reduce excessive inventory, lower warehousing costs, while ensuring sufficient inventory to meet demand and improve the inventory turnover rate.

[0150] By adjusting the inventory to adapt to the usage frequency and failure rate of standard segments, enterprises can better cope with the supply interruption risk caused by standard segment failures. This helps ensure the continuity of production and reduce losses caused by standard segment failures.

[0151] This method can help enterprises reasonably allocate inventory resources among different standard segments. By maintaining a higher inventory for standard segments with high usage frequency and reducing inventory for standard segments with low usage frequency, enterprises can utilize limited resources more effectively.

[0152] The inventory optimization calculation method provides a quantitative basis to help decision-makers formulate inventory strategies more scientifically. By adjusting the weight coefficients, enterprises can flexibly balance the impacts of different factors according to their own situations and make decisions that better meet actual needs.

[0153] By optimizing inventory management, enterprises can respond to customer demands more quickly, reduce out-of-stock situations, improve the timeliness and reliability of product supply, thereby enhancing customer satisfaction and loyalty.

[0154] The inventory optimization calculation method encourages enterprises to continuously monitor and analyze indicators such as the usage frequency, failure rate, and inventory turnover rate of standard segments, so as to identify improvement opportunities, continuously optimize the inventory management strategy, and achieve continuous improvement.

[0155] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it is understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
