Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to the technical field of temporary power supply for building construction, and specifically refers to a turnaround power supply module for temporary power supply for building construction. Background Art

[0002] Building construction refers to the production activities during the implementation phase of a project. It is the process of constructing various buildings. It can also be said to be the process of transforming the various lines on the design drawings into physical objects at the designated location. It includes foundation construction, main structure construction, roof construction, and decorative construction.

[0003] Electricity is a crucial energy source for construction, consumed across all phases of the project. This is particularly true for construction machinery and equipment, which largely rely on electricity as their primary energy source. This includes large-scale construction machinery like tower cranes, mortar mixers, and construction elevators, as well as smaller equipment like rebar shears, welders, electric drills, electric jackhammers, and water pumps. According to statistics from the China Electricity Council, national industrial electricity consumption reached 597.79 billion kWh in 2023, a year-on-year increase of 7.96%. While the growth rate of the construction industry has slowed due to structural adjustments, electricity consumption remains high. With the increase in building size and the sophistication of construction equipment, the proportion of electricity consumed by small on-site equipment has gradually increased. This has led to increasingly complex temporary power supply arrangements and increased difficulty in balancing power supply requirements across different work areas. Therefore, addressing the challenges of deploying temporary power supply systems under complex working conditions and proposing a rapid temporary power supply system technology that improves the mobility of mobile power supply systems is of great practical significance for accelerating construction schedules and reducing labor and material inputs.

[0004] Currently, temporary power supply for construction is mainly achieved by setting up distribution cabinets and wiring on site to meet the power needs of different work surfaces. This method has the advantage of stable power output, but it also has many disadvantages, including:

[0005] 1) According to the temporary power layout and power distribution on site, the power should be led out from the adjacent secondary box and then to the tertiary box. There are many cables, which are staggered, resulting in high wire consumption and easy damage.

[0006] 2) The on-site construction environment is relatively complex. For example, when working in basements and other locations prone to water accumulation and leakage, long cables can easily cause leakage and power outages, affecting on-site power safety. For working conditions where distribution cabinets cannot be arranged in a small space, multiple pulls from the remote end are required to connect to the power supply, which is not conducive to on-site construction. For outdoor working conditions with sporadic power consumption without grid access, power generation equipment must be configured simultaneously for power supply. However, power generation equipment is usually not suitable for mobile operations, affecting construction efficiency.

[0007] 3) The working area is limited by the location of the tertiary box and the electrical cables. It is necessary to constantly move the electrical box or add or modify the circuit, which limits flexibility and low working efficiency. In some construction areas, electrical boxes cannot be arranged, and construction is hindered.

[0008] 4) For temporary power supply methods using traditional on-site distribution cabinets and wiring, some cordless tools are gradually being used on-site to replace traditional wired power tools to improve mobile construction capabilities. Common cordless construction tools include electric wrenches, handheld cordless drills, and cordless angle grinders. However, these charging devices are limited by factors such as power intensity, battery capacity, and operating scenarios. The power supply continuity cannot fully meet on-site needs, which limits the use of construction tools.

[0009] Therefore, it is hoped to provide a revolving power supply module for temporary electricity use in construction, which can realize the rapid construction of temporary electricity use, improve the mobility and flexibility of mobile electricity use, reduce the movement and modification of distribution boxes, and increase the ability of construction mobile and rapid operation.

[0055] The assembly steps of this utility model are briefly described as follows:

[0056] S1. Analyze the temporary power supply situation at the construction site, study the temporary power supply layout for conventional project construction, focus on analyzing the sub-projects and specific processes with characteristics such as multiple points and wide coverage, non-fixed locations, and large differences in power consumption, establish a parameter table of power type, power parameters, and application frequency for construction machinery and tools for temporary power supply of such tasks, determine the specific scenarios in which the utility model can be applied based on the formed parameter table, screen conventional and high-frequency construction machinery and tools, and provide a basis for determining the parameters of the utility model.

[0057] S2. The present utility model is designed according to temporary power conditions and a collection of construction machinery and tools. Its core components include: energy storage unit 2, inverter 3, control system 4, and other auxiliary components. First, the battery type and capacity of the energy storage unit 2 should be determined. Based on the applicability analysis of various types of batteries, it is advisable to select a battery type with large capacity, small size, light weight, and stable output at the construction site. The inverter 3 model and specifications are selected based on the charging and discharging mechanism to meet the working conditions of high charging and discharging times, fast charging speed, high frequency, large power demand of machinery and tools, and large instantaneous voltage and current during construction. The control system 4 is selected to perform overall control of the entire power supply module. The auxiliary components are determined, including: chassis 1, charging and discharging interface module 7, cooling system 5, monitoring system 6, etc.

[0058] S3. Assemble the energy storage unit 2. The energy storage unit 2 is formed by connecting multiple battery cells 8 together to form the entire energy storage unit 2. The energy storage unit 2 is the core module and must possess high performance, including energy storage capacity, power supply stability, and energy storage efficiency. However, a balance must be struck between efficient energy storage and cost. Energy storage units 2 that are safe, stable, adaptable to construction requirements, and reasonably cost-effective should be selected. During the assembly phase, the battery cells 8 are connected together by welding connecting plates 9, which are then connected to the control system 4.

[0059] S4. Assemble inverter 3. Inverter 3 is a key component for AC / DC conversion in the power supply module. During assembly, select a model with high conversion efficiency and stable performance, and allow for sufficient protection margin to prevent damage from current overloads and shocks. Inverter 3 not only performs AC / DC conversion for charging and discharging energy storage unit 2, but also adapts to the current requirements of external construction equipment, ensuring greater field adaptability for the entire power supply module. During assembly, inverter 3 is connected to energy storage unit 2 and control system 4, which provides unified control.

[0060] S5, control system 4, is the core component that controls the entire power supply module. This can take the form of a control motherboard. In addition to basic input and output control functions, it must also provide responsiveness, intelligent protection, fault diagnosis, and stable power output. Assemble control system 4 and connect all components to it. These components primarily include: energy storage unit 2, inverter 3, cooling system 5, monitoring system 6, and charge / discharge interface module 7. Control system 4 provides unified control of the power supply module's operation.

[0061] S6. Install the power supply module's auxiliary components, primarily determining the type and quantity of each interface in the charge-discharge interface module 7. Select and install the cooling system 5 based on factors such as power, layout, and heat dissipation. Dimension the chassis 1 based on the assembly of these components. The chassis 1 should be constructed of durable, impact-resistant, deformation-resistant, and strong and rigid materials and specifications, and waterproof, fireproof, and insulated. Monitoring system 6 ensures the safety and stability of the entire system. This completes the initial assembly of the power supply module, followed by performance testing to ensure it meets the construction site's application standards.

[0062] S7. The temporary power supply module for construction is formed. During the simultaneous construction phase of multiple working surfaces and multiple types of work, temporary power points are numerous and widespread, with unstable locations and large differences in power consumption. These points are prone to problems such as non-standardization, messy cables, excess electrical boxes, and low construction efficiency. In order to reduce the complexity of traditional on-site temporary power layout and reduce the power supply pressure of temporary power lines, the power supply module of the present invention is used in combination with the characteristics of temporary power in construction to overcome the application problems of temporary power layout in complex working conditions, reduce the movement and modification of distribution boxes, reduce the number of on-site electrical boxes, realize the rapid construction of temporary power, improve the mobility and flexibility of mobile power, and increase the ability of mobile and rapid construction operations. In combination with the power range and usage intensity of on-site construction machinery, the power supply module is used to expand the application scenarios and work continuity of small construction machinery and reduce the restrictions of traditional temporary power layout on construction machinery and reduce the cost and power loss of long-distance temporary power lines, thereby improving the efficiency and safety of outdoor temporary power operations. The power supply module adopts a modular design and processing concept to reduce weight and volume, facilitate on-site assembly, disassembly and maintenance, and has high on-site adaptability, versatility and durability to meet temporary power needs during construction.

[0063] When in use, the utility model is placed at a temporary power supply location, and the power connector (e.g., a power plug) of the construction machinery and equipment is inserted into the discharge interface (e.g., a three-hole socket 12) of the charge and discharge interface module 7. The DC power in the energy storage unit 2 is converted into AC power by the inverter 3 and transmitted to the discharge interface through the control system 4, thereby powering the construction machinery and equipment. When the energy storage unit 2 needs to be charged, the charging connector is inserted into the charging interface 10 of the charge and discharge interface module 7, and the plug connected to the charging connector is inserted into the socket connected to the mains power. The mains power is transmitted to the control system 4 through the charging interface 10, and then transmitted to the inverter 3 through the control system 4. The AC power (i.e., the mains power) is converted into DC power by the inverter 3 and charged into the energy storage unit 2. During the above-mentioned use process, the internal space of the chassis 1 is cooled by the cooling system 5, and the various parameter states of the power supply module are monitored by the monitoring system 6, such as the capacity and output and input voltage and current values ​​of the energy storage unit 2, the temperature and humidity of the internal space of the chassis 1, etc., and sent to the control system 4. After receiving these data, the control system 4 can perform relevant controls according to these data and the preset values ​​of the corresponding parameters, for example:

[0064] If the capacity of the energy storage unit 2 reaches, for example, less than 20% of the maximum capacity of the energy storage unit 2, the control system 4 can prompt the staff, for example, through an indicator light, that the energy storage unit 2 needs to be charged; if the capacity of the energy storage unit 2 reaches the maximum capacity of the energy storage unit 2, the control system 4 stops charging the energy storage unit 2 and can prompt the staff, for example, through an indicator light, that the energy storage unit 2 has been fully charged;

[0065] If the output and input voltage and current values ​​of the energy storage unit 2 exceed the rated voltage and current of the energy storage unit 2, the control system 4 stops the input and output of the energy storage unit 2 and can alert the staff through, for example, an alarm.

[0066] If the temperature of the interior space of the chassis 1 exceeds the maximum set value, the control system 4 stops the input and output of the energy storage unit 2 and can alert the staff through, for example, an alarm, and cools the interior space of the chassis 1 through the cooling system 5; if the temperature of the interior space of the chassis 1 is lower than the minimum set value, the control system 4 stops the input and output of the energy storage unit 2 and can alert the staff through, for example, an alarm, and stops the cooling system 5;

[0067] If the humidity of the internal space of the chassis 1 exceeds a set value, the control system 4 stops the input and output of the energy storage unit 2 and can alert the staff through, for example, an alarm.

[0068] Temporary power supply at construction sites is used throughout the entire construction phase, and most equipment and tools rely on electricity to operate. Conventional on-site temporary power supply typically utilizes a distribution box and traction cables to form a network. During the simultaneous construction phase involving multiple work surfaces and multiple types of work, temporary power supply is characterized by numerous locations, unstable locations, and significant variations in power consumption. This can lead to irregularities in on-site temporary power supply, cluttered cables, an excess of electrical boxes, and low construction efficiency. To mitigate the adverse effects of these issues, a mobile power supply device should be proposed that can both meet the power needs of most on-site construction equipment and adapt to the flexible power supply requirements of multiple locations. This reduces the complexity of traditional on-site temporary power supply arrangements and reduces the pressure on temporary power lines. Based on this, the utility model designs and manufactures a reusable power supply module based on the characteristics of temporary power supply operations during on-site construction. This reduces the number of distribution boxes and lines, improves the flexibility and maneuverability of temporary power supply, effectively improves the efficiency of mobile operations, and provides high power supply stability and strong output continuity. At the same time, it overcomes the safety risks of multiple traction wiring and long-distance power supply, reduces labor and material investment, and has a standardized design that is easy to assemble and disassemble. The equipment has high durability, fast maintenance, and multiple turnovers. It is a new device that supplements traditional temporary power supply for construction. Its innovative points are as follows:

[0069] 1) The present invention is a device based on the principle of energy storage technology and the concept of mobile temporary power supply. It uses an energy storage unit composed of multiple battery units and is a portable power supply system for construction sites. The present invention aims to reduce the complexity of traditional temporary power supply arrangements on site and reduce the power supply pressure of temporary power lines. The application of this power supply module in construction can reduce the investment in cable materials and distribution boxes. Especially for the decoration and renovation stage, where multiple types of work and multiple points are cross-constructed and there are many small machines and tools, the application of this power supply module can improve construction efficiency and achieve the goal of an average replacement rate of 30% to 50% for three-level distribution boxes during the decoration and renovation stage.

[0070] 2) This utility model combines a lightweight and mobile design concept, with the core aim of improving the mobility and flexibility of the power supply module.
