[0002] Elevator energy-saving systems are used to recover and utilize the regenerative electrical energy generated during elevator operation. Existing elevator energy-saving systems mostly adopt an integrated cabinet structure, concentrating power management and energy storage battery modules within a single cabinet. However, given the increasing prevalence of machine-room-less elevators and the limited space in existing building machine rooms, this integrated structure has significant drawbacks: firstly, the equipment is bulky, making it difficult to adapt to the installation requirements of narrow spaces, and the centralized layout makes heat dissipation difficult in a confined environment, easily triggering overheat protection and affecting operational safety; secondly, the high degree of coupling between functional modules means that in the event of a partial failure, the entire system often needs to be disassembled for repair, resulting in low maintenance efficiency.

[0055] Combination Figure 1 and Figure 2The elevator energy-saving system disclosed in this application is used to realize the recovery and storage of elevator energy. It includes a power management module 100, an energy storage battery module 200, and electrical connection components. The power management module 100 includes a first housing 110, an electrical control component 120, and a first interface component 130. The first housing 110 is provided with a first panel 113. The electrical control component 120 is disposed within the first housing 110 and is used to realize power distribution, system protection and control, and signal detection. The first interface component 130 is disposed on the first panel 113 and is electrically connected to the electrical control component 120. The energy storage battery module 200 is used to store regenerated electrical energy generated during elevator operation and includes a second... The system comprises a housing 210, a battery pack, a battery management component, and a second interface component 220. The housing 210 has a second panel 213. The battery pack is used for energy storage, and the battery management component is used to monitor and protect the battery pack's status in real time, ensuring efficient charging and discharging within a safe range. Both the battery pack and the battery management component are housed within the housing 210 and are electrically connected to each other. The second interface component 220 is located on the second panel 213 and is electrically connected to both the battery pack and the battery management component. An electrical connection component is electrically connected between the first interface component 130 and the second interface component 220 for transmitting electrical energy and exchanging signals. Specifically, the battery management component is communicatively connected to the electronic control component 120 to send data such as the remaining battery capacity, health status, and maximum allowable charging and discharging power of the battery pack to the electronic control component 120, and simultaneously receives instructions from the electronic control component 120. The battery pack and the electronic control component 120 are electrically connected to form a physical path for actual energy transmission.

[0056] Combination Figures 3-6 The number of the aforementioned energy storage battery modules 200 can be one or more, and they can be installed in a horizontal or vertical combination according to the actual space scenario.

[0057] Compared to existing technologies, the elevator energy-saving system disclosed in this application adopts a modular structure, which allows the power management module 100 and the energy storage battery module 200 to be flexibly distributed and installed according to the installation space. This effectively utilizes fragmented space to solve the installation problems of machine room 310 and narrow machine room 310. On this basis, the independent heat dissipation of the power management module 100 and the energy storage battery module 200 is achieved through functional decoupling to adapt to special thermal environments, while ensuring installation and maintenance efficiency and enabling flexible expansion.

[0058] Specifically, the first interface component 130 includes a first power interface 131 and a first communication interface 132. The first power interface 131 is electrically connected to the power terminal of the electronic control component 120 to form a power supply circuit, thereby enabling power input and output. The first communication interface 132 is electrically connected to the signal terminal of the electronic control component 120 to achieve signal interaction. The second interface component 220 includes a second power interface 221 and a second communication interface 222. The second power interface 221 is electrically connected to the cell terminal of the battery component to form a charging and discharging circuit, thereby enabling power input and output. The second communication interface 222 is electrically connected to the communication terminal of the battery management component to achieve signal interaction. The electrical connection component includes a first power connection cable and a first communication connection cable. The first power connection cable is electrically connected between the first power interface 131 and the second power interface 221, and the first communication connection cable is electrically connected between the first communication interface 132 and the second communication interface 222.

[0059] To ensure efficient disassembly and maintenance, quick-connect connectors can be used between the first power interface 131 and the second power interface 221 and the first power connection cable, as well as between the first communication interface 132 and the second communication interface 222 and the first communication connection cable, to enable rapid connection and fault isolation. Furthermore, the first power interface 131, the second power interface 221, the first communication interface 132, and the second communication interface 222 can be positioned and inserted into the quick-connect connectors using a concave-convex structure to prevent incorrect connection and ensure that the positive and negative terminals are not reversed. The insertion and extraction force is controlled between 20N and 30N to ensure that a single person can quickly complete the insertion and extraction.

[0060] For example, the battery management component described above may include a BMU (Battery Management Unit), the detection end of which is electrically connected to the battery assembly to monitor the status of the battery assembly, and the second communication interface 222 is electrically connected to the communication end of the BMU.

[0061] The aforementioned electronic control component 120 may include a BCU (Battery Control Unit), and components such as a relay, circuit breaker 121, fuse, and meter 122 electrically connected to the BCU. The BCU, relay, and fuse are all housed in the first enclosure 110, while the circuit breaker 121 and meter 122 are housed on the first panel 113. The circuit breaker 121 and fuse are connected in series in the power supply circuit between the first power interface 131 and the BCU. The meter 122 is used to detect the power information of the power supply circuit, and the relay is controlled by the BCU to switch the power supply circuit on and off.

[0062] In some embodiments, the power management module 100 further includes a control component 140, which includes an indicator light and an emergency stop button. Both the indicator light and the emergency stop button are located on the first panel 113. The indicator light is electrically connected to the BCU to display the BCU's operating status, and the emergency stop button is electrically connected to the BCU to trigger the BCU control relay to disconnect the power supply circuit. By ensuring that there are no excessively protruding parts on the first panel 113, interference from bumps during installation can be avoided.

[0063] The layout of the components on the first panel 113 can be adjusted according to the layout of the electronic control components 120 inside the first housing 110. Figure 1 The diagram illustrates a layout scheme for a first panel 113, featuring a left-strong, right-weak voltage partition. A first power interface 131 is located on the lower left side of the first panel 113, a first communication interface 132 is located on the lower right side, a circuit breaker 121 and a meter 122 are located on the upper left side, and an indicator light and an emergency stop button are located on the upper right side. The first panel 113 may include a first strong voltage zone and a first weak voltage zone. The first power interface 131 is located in the first strong voltage zone, and the first communication interface 132 is located in the first weak voltage zone. A first isolation distance is provided between the first strong voltage zone and the first weak voltage zone to meet safety production requirements. A second panel 213 includes a second strong voltage zone and a second weak voltage zone. A second power interface 221 is located in the second strong voltage zone, and a second communication interface 222 is located in the second weak voltage zone. A second isolation distance is provided between the second strong voltage zone and the second weak voltage zone to meet safety production requirements. For example, the first isolation distance is ≥90mm to ensure that the first communication interface 132 and the first power interface 131 maintain a distance of at least 90mm to avoid interference.

[0064] In addition, when there are multiple first power interfaces 131 and second power interfaces 221, the distance between each first power interface 131 and the distance between each second power interface 221 also meet the requirements for safe production; when there are multiple first communication interfaces 132 and second communication interfaces 222, the distance between each first communication interface 132 and the distance between each second communication interface 222 also meet the requirements for safe production.

[0065] For example, the electrical clearance between each first power interface 131 at the AC380V / DC600V level is ≥12mm, and the creepage distance is ≥14mm, meeting national standards. Furthermore, the interface terminals of the first power interface 131 are made of insulating material to achieve insulation protection and prevent accidental contact. The electrical clearance between each first communication interface 132 at the DC24V level is ≥6mm, and the creepage distance is ≥8mm. Further, the spacing between each first power interface 131 and each first communication interface 132 is ≥20mm to facilitate installation and plugging / unplugging operations; and the edge distance between each first power interface 131 and each first communication interface 132 and the power management module 100 is ≥50mm to prevent the first power connection cable and the first communication connection cable from squeezing the interface root when bent, thus improving connection reliability.

[0066] Figure 2 The diagram illustrates a technical solution where a second low-voltage zone is located on the upper part of the second panel 213, and a second high-voltage zone is located on the lower part of the second panel 213. The distance between the second low-voltage zone and the second high-voltage zone is ≥20mm, which facilitates the installation and plugging / unplugging of the first communication connection cable and the first power connection cable. The distance between the second power interface 221 and the second communication interface 222 and the edge of the energy storage battery module 200 is ≥50mm, so as to avoid the first power connection cable and the first communication connection cable from squeezing the root of the interface when bending, thereby improving the reliability of the connection.

[0067] To protect the first communication connection cable and the first power connection cable, the electrical connection assembly also includes at least two flexible sleeves, which are respectively fitted over the first power connection cable and the first communication connection cable. The flexible sleeves can be corrugated pipes, braided mesh pipes, polytetrafluoroethylene pipes, etc., thereby providing reliable protection for the cables.

[0068] To standardize wiring, the electrical connection assembly may also include an insulated cable tray. The insulated cable tray is provided with a first tray and a second tray. The first power connection cable is placed in the first tray and the first communication connection cable is placed in the second tray, thereby achieving physical isolation between strong and weak currents. This effectively prevents electromagnetic interference generated by the first power connection cable when transmitting high current from entering the first communication connection cable and causing signal distortion. At the same time, the dual-tray structure can provide reliable mechanical protection and positioning for the cables.

[0069] To improve heat dissipation performance, the aforementioned energy storage battery module 200 may further include a heat dissipation component, which includes a cooling fan. The cooling fan is disposed within the second housing 210 and is used to blow air to dissipate heat from the battery module and the battery management component. The second housing 210 has heat dissipation holes 214 that are arranged corresponding to the cooling fan and communicate with the outside. Figure 2The heat dissipation hole 214 can be specifically formed on the second panel 213, and the number of heat dissipation holes 214 can be one or more, which is not limited in this application. Of course, depending on the actual operating conditions, the power management module 100 can also be equipped with a heat dissipation component to ensure the normal operation of the electronic control component 120.

[0070] For ease of maintenance, the first enclosure 110 may include a first enclosure body 111 and a first cover plate 112. The first enclosure body 111 is provided with the first panel 113, and the electronic control component 120 is disposed within the first enclosure body 111. A first sliding groove is provided at the top opening of the first enclosure body 111, and the first cover plate 112 is slidably installed with the first sliding groove, thereby facilitating the inspection and maintenance of the electronic control component 120 within the first enclosure 110. Similarly, the second enclosure 210 includes a second enclosure body 211 and a second cover plate 212. The second enclosure body 211 is provided with the second panel 213, and both the battery assembly and the battery management component are disposed within the second enclosure body 211. A second sliding groove is provided at the opening of the second enclosure body 211, and the second cover plate 212 is slidably installed with the second sliding groove, thereby facilitating the inspection and maintenance of the battery assembly and the battery management component. One side of the first housing body 111 can be used as the first panel 113, and one side of the second housing body 211 can be used as the second panel 213.

[0071] The first housing 110 can be bolted to a fixed bracket or slidably mounted on a sliding rail. To facilitate manual handling and installation of the power management module 100, a first handle 114 can be provided on the outer wall of the first housing 110. The first handle 114 can be located at the bottom or side of the first housing 110 for easy operation. The first handle 114 can also be a retractable or foldable U-shaped structure. When folded, the first handle 114 is close to the first housing 110, and when unfolded, the first handle 114 protrudes from the surface of the first housing 110. Specifically, the distance between the first handle 114 and the edge of the first panel 113 can be 20mm, the width is 50mm, and the grip distance is 90mm to fit the size of an adult's hand, ensuring that a single person can easily move, slide the power management module 100 into the sliding rail, or remove it for maintenance using the first handle 114.

[0072] To facilitate manual handling of the energy storage battery module 200, a second handle 215 is provided on the outer wall of the second housing 210. The second handle 215 can adopt a foldable U-shaped structure, and the layout of the second handle 215 on the second panel 213 can be consistent with the layout of the first handle 114 on the first panel 113, which will not be described in detail here.

[0073] To facilitate manual handling, heat dissipation of internal components, and reduce space occupation, the first box 110 and the second box 210 can adopt a thin box structure. The first box 110 and the second box 210 can be wall-mounted or floor-mounted to be suitable for various narrow spaces such as the top of the elevator shaft 300, the top of the car 321, the interior of the decorative panel above the landing door, the wall of the machine room 310, or the side of the existing elevator control cabinet 323. Figure 1 The diagram illustrates a technical solution where the length, width, and height of the first housing 110 are greater than 250 mm. The length and height of the second housing 210 can be the same as those of the first housing 110, and the width of the second housing 210 can be less than that of the first housing 110, to facilitate the side-by-side installation and connection of the power management module 100 and the energy storage battery module 200, as well as the combined installation of multiple energy storage battery modules 200.

[0074] The elevator energy-saving system disclosed in this application has the following advantages:

[0075] Firstly, it has strong spatial adaptability: through functional decoupling and modular design, the elevator energy-saving system is broken down into small independent modules. The volume of a single module does not exceed 0.07m³ and the weight is ≤30kg. It can be embedded in fragmented spaces such as the side wall of the elevator shaft 300 and scattered corners of the machine room 310, solving the problem of limited installation space in the absence of a machine room 310 or in a narrow machine room 310, and improving the space utilization rate by more than 60%.

[0076] Secondly, it has efficient heat dissipation and optimized scenarios: each module can dissipate heat independently, and the heat dissipation area is increased by 40% compared with the traditional whole cabinet. Through the active and passive heat dissipation design of the energy storage battery module 200, the working temperature of the energy storage battery module 200 can be reduced by 15℃-25℃, avoiding the problem of overheating in a closed space, and adapting to special thermal environments such as no server room 310 and narrow server room 310.

[0077] Thirdly, installation and maintenance are convenient: the weight of a single module is ≤30kg, which can be carried by a single person. At the same time, it can be quickly installed, and the assembly time can be shortened by 1 / 3 compared with the whole cabinet structure. In case of failure, only the faulty module needs to be disassembled, without the need for overall disassembly and assembly, which improves maintenance efficiency by 80% and reduces labor costs.

[0078] Fourth, high reliability and scalability: The modules are connected by quick-plug connectors, which can achieve fault isolation. The failure of a single module will not affect the overall operation of the elevator energy-saving system, thus improving the fault tolerance of the elevator energy-saving system. The capacity can be expanded by increasing the number of energy storage battery modules by 200 without replacing the core components, which can protect the user's initial investment and increase the value retention rate by more than 50%.

[0079] The elevator energy-saving system installation method disclosed in this application is used to install the aforementioned elevator energy-saving system, and includes the following steps:

[0080] S10. Spatial Avoidance Planning: This involves defining the load-bearing base for the elevator energy-saving system and delineating its installation area on the base. This installation area must avoid the operating envelope of the car 321 and counterweight 322, as well as moving elevator components such as traction cables, compensating chains, and safety brakes. A maintenance access route for the elevator energy-saving system is also provided. By pre-delineating the avoidance envelope and installation area for moving elevator components on the load-bearing base and reserving maintenance access, the risk of physical collision between the new elevator energy-saving system and the existing elevator foundation system is eliminated from the outset, ensuring the safety of elevator operation and providing maintenance personnel with a safe operating space that meets standards.

[0081] S20. Assemble the support bracket. Install the support bracket on the support base and check the horizontality and verticality of the support bracket to ensure that there is no structural interference between the support bracket and the elevator foundation system. This will provide a stable and stress-free installation base for the subsequent power management module 100 and energy storage battery module 200, and prevent the module from slipping or generating destructive additional bending moments on the support base due to the tilt of the support bracket.

[0082] S30. The modules are positioned and fixed. According to the preset spatial layout strategy, the power management module 100 and the energy storage battery module 200 are respectively assembled in the installation area of ​​the support bracket. A heat dissipation gap is reserved between the power management module 100 and the energy storage battery module 200 to avoid the risk of heat accumulation and thermal runaway between the power management module 100 and the energy storage battery module 200. At the same time, it is ensured that the overall center of gravity of the power management module 100 and the energy storage battery module 200 are within the bearing range of the support base, so that the gravity load of the entire elevator energy-saving system can be safely and evenly distributed on the support base, preventing excessive local stress from causing structural deformation or detachment.

[0083] S40. Wiring: Electrically connect the power management module 100 and the energy storage battery module 200 through electrical connection components; then electrically connect the power management module 100 to the elevator control cabinet 323 through external cables.

[0084] Specifically, quick-plug connectors are used to connect the first power interface 131 and the second power interface 221 to the first power connection cable, and to connect the first communication interface 132 and the second communication interface 222 to the first communication connection cable. This avoids short circuits and burnouts caused by incorrect wiring during on-site construction and improves assembly efficiency. Furthermore, the first power connection cable and the first communication connection cable are laid separately to maintain anti-interference spacing, avoiding electromagnetic interference from high-voltage currents to weak-voltage communication signals and ensuring system communication stability. The first power connection cable, the first communication connection cable, and external cables are fixed along an alternative path to prevent insulation damage and leakage caused by wind swaying or long-term friction with moving elevator parts in the complex shaft 300 or machine room 310 environment. The external cables maintain an isolation distance from the first power connection cable to ensure electromagnetic compatibility between the elevator energy-saving system and the elevator foundation system.

[0085] S50, Safety and Performance Verification, performs insulation and grounding tests on the power management module 100 and the energy storage battery module 200; simulates elevator operation and verifies that there is no spatial interference in the installation area, that the heat dissipation of the power management module 100 and the energy storage battery module 200 meets the standards, and that the communication signal between the elevator energy-saving system and the control cabinet 323 is stable. S60 enables comprehensive verification of the entire elevator system, effectively ensuring the reliability and safety of elevator operation.

[0086] Compared with the prior art, the elevator energy-saving system installation method disclosed in this application can realize the reliable installation and stable operation of the elevator energy-saving system in a variety of application scenarios, while not interfering with the elevator foundation system.

[0087] Combination Figure 3 and Figure 4In some embodiments, in S10, the supporting base is a transverse guide rail 301 connected to the top of the two elevator guide rails. The elevator guide rail is the guide rail for the car 321 during operation. The installation area and the traction machine 320 are arranged side by side along the extension direction of the transverse guide rail 301, and a vibration-damping gap is reserved between the installation area and the traction machine 320. The supporting bracket includes a load-bearing arm. In S20, the load-bearing arm is installed on the transverse guide rail 301, and the horizontality and verticality of the load-bearing arm are checked to ensure that there is no structural interference between the load-bearing arm and the elevator foundation system. The spatial layout strategy in S30 is that the power management module 100 and the energy storage battery module 200 are arranged sequentially along the length direction of the transverse guide rail 301 and installed on the load-bearing arm to recover elevator energy nearby, while avoiding the high-frequency mechanical vibration of the traction machine 320 from affecting the normal operation of the elevator energy-saving system. The load-bearing support arm can be installed on the transverse guide rail 301 by means of bolt connection, welding, etc. The power management module 100 and the energy storage battery module 200 can each correspond to one load-bearing support arm. Furthermore, positioning holes can be opened on the power management module 100 and the energy storage battery module 200, and positioning protrusions corresponding to the positioning holes can be set on the load-bearing support arm to realize the positioning installation of the power management module 100 and the energy storage battery module 200 with the load-bearing support arm. Of course, the positioning protrusions and positioning holes can be interchanged, that is, positioning protrusions can be set on the power management module 100 and the energy storage battery module 200, and positioning holes can be opened on the load-bearing support arm without affecting the realization of its function.

[0088] In other embodiments disclosed in this application, combined with Figure 5 and Figure 6In S10, the supporting base consists of a first wall and a second wall located opposite or adjacent to each other within the machine room 310. The first wall is the wall where the elevator control cabinet 323 is located, and the second wall is the wall opposite the machine room door 311 of the machine room 310. The supporting bracket includes a fixed bracket and a sliding guide rail. In S20, the fixed bracket is installed on the first wall, and the sliding guide rail is installed on the second wall. Then, the horizontality and verticality of the fixed bracket and the sliding guide rail are checked, while ensuring that the fixed bracket and the sliding guide rail do not structurally interfere with the elevator's foundation system. In S30, the spatial layout strategy is that the power management module 100 is installed on the fixed bracket, and the first interface component 130 faces the control cabinet. In layout 323, the energy storage battery module 200 is mounted on a sliding guide rail with the second interface component 220 facing the maintenance passageway inside the equipment room 310. The energy storage battery module 200 can be directly slid in along the extension direction of the sliding guide rail for installation and locked by a positioning pin, thereby reducing on-site construction labor costs and lowering the risk of personnel falling. It also facilitates quick insertion and replacement in case of module failure. In S40, electrical connection components and external cables are routed along the walls inside the equipment room 310, with transition protective components installed at corners. This corner-based routing minimizes the exposed area of ​​the cables, avoiding obstruction of floor passageways and significantly enhancing the cables' resistance to trampling and collisions. The transition protective components can be corner protectors or elbows.

[0089] In some embodiments, S60 also includes a fault isolation test, which specifically involves disconnecting the power management module 100 and the energy storage battery module 200 from other devices to verify the operating status of the remaining modules and the original elevator system after a single module is disconnected, confirming that rapid physical-level fault isolation can be achieved, and ensuring that the faulty module will not affect the normal operation of the original elevator system.

[0090] Figure 3 and Figure 4 The diagram illustrates an installation scheme for an elevator energy-saving system within a machine-room-less elevator shaft 300 (310). The traction machine 320 is fixed to the heavy-duty elevator transverse guide rail 301 at the top landing of the shaft 300 via a dedicated mounting bracket. The control cabinet 323 is installed on the side wall of the shaft 300 next to the top landing door. The top clearance of the shaft 300 is 1100mm-1500mm. The transverse guide rail 301 is a T75 heavy-duty guide rail with a load-bearing capacity ≥2000kg, providing sufficient installation redundancy. The power management module 100 and the energy storage battery module 200 avoid the operating envelope area of ​​the car 321 and counterweight 322, and a safety maintenance station space of ≥600mm is reserved. The installation process is as follows:

[0091] In S10, using the transverse guide rail 301 as a reference, an installation area parallel to the traction machine 320 is defined. That is, the installation area is located on one side of the traction machine 320 along the extension direction of the transverse guide rail 301. It is ensured that the distance between the subsequent power management module 100 and the energy storage battery module 200 and the traction machine 320 along the extension direction of the transverse guide rail 301 is ≥300mm to avoid vibration transmission and electromagnetic interference during the operation of the traction machine 320. At the same time, it is ensured that the distance between the subsequent power management module 100 and the energy storage battery module 200 and the side wall of the shaft 300 is ≥200mm to reserve sufficient heat dissipation space and wiring space. The distance between the power management module 100 and the energy storage battery module 200 and the top of the shaft 300 is greater than ≥200mm to reserve sufficient heat dissipation space and maintenance operation redundancy. In addition, the installation areas of the power management module 100 and the energy storage battery module 200 should avoid the operating envelope area of ​​the car 321 and the counterweight 322, and be ≥200mm away from the edge of the envelope area. At the same time, ensure that the front of the power management module 100 and the energy storage battery module 200 has ≥600mm of maintenance and operation space to meet the national standard maintenance space requirements.

[0092] In S20, guide rail adapter components are selected and fixed. Customized load-bearing brackets that match the T75 type transverse guide rail 301 are adopted. The load-bearing brackets can be integrated bending structures. The load-bearing capacity of a single load-bearing bracket is ≥100kg, and the safety factor is ≥3, in order to adapt to the total weight of the elevator energy-saving system and the additional load of maintenance. The length of the load-bearing brackets is adapted to the transverse guide rail 301 to ensure that the center of gravity of each module falls within the load-bearing range of the transverse guide rail 301 after installation. Then, the guide rail adapter components are installed. Based on the installation positions of the power management module 100 and the energy storage battery module 200, the mounting holes are marked on the transverse guide rail 301. High-strength bolts are used to tighten the load-bearing brackets, and the spacing of the load-bearing brackets is adapted to the width of the modules. After installation, a level is used to check and ensure that the horizontal error of the load-bearing brackets is ≤1mm and the vertical error is ≤1mm. The load-bearing capacity of a single set of load-bearing brackets is tested with a tension gauge to ensure that there is no risk of loosening or slippage. At the same time, the distance between the traction machine 320 fixed seat and the load-bearing brackets is checked to ensure that there is no structural interference.

[0093] In S30, module installation is performed. A single person uses the first handle 114 and the second handle 215 to move the power management module 100 and the energy storage battery module 200. First, the power management module 100 is placed stably on the corresponding load-bearing support arm. The position of the power management module 100 is adjusted so that its bottom positioning hole is fitted with the positioning protrusion on the load-bearing support arm. The power management module 100 is then connected to the corresponding load-bearing support arm using bolts. Next, the energy storage battery module 200 is placed next to the power management module 100 on another set of load-bearing support arms. The above fixing process is repeated, and the distance between the power management module 100 and the energy storage battery module 200 is ≥150mm to leave sufficient heat dissipation gap. At the same time, the power management module 100 and the energy storage battery module 200 are aligned along the extension direction of the transverse guide rail 301 to prevent the center of gravity of the power management module 100 and the energy storage battery module 200 from exceeding the load-bearing support surface of the transverse guide rail 301. After installation, use a level to check the levelness of the first panel 113 and the second panel 213 to ensure that the error is ≤1mm. Use a tape measure to measure whether the distance between the power management module 100, the energy storage battery module 200 and the traction machine 320 meets the requirements. Finally, place a 50kg counterweight on top of the power management module 100 and the energy storage battery module 200, and observe whether the transverse guide rail 301 is deformed and whether the load-bearing bracket is displaced through a no-load loading test to ensure that the load-bearing and relative position requirements are met.

[0094] In S40, electrical connections are made between the power management module 100 and the energy storage battery module 200, and cables are laid between the elevator energy-saving system and the elevator foundation system. First, the electrical connection between the power management module 100 and the energy storage battery module 200 is established: both ends of the first power connection cable are connected to the first power interface 131 and the second power interface 221 respectively, and locked using quick-plug connectors. The quick-plug connectors automatically lock after insertion / removal to prevent accidental detachment. Then, both ends of the first communication connection cable are connected to the first communication interface 132 and the second communication interface 222 respectively. The first communication connection cable can be a shielded twisted-pair cable and is laid separately from the first power connection cable, ensuring a distance of ≥50mm between them. The communication interface 132 and the second communication interface 222 can use foolproof connectors, and the nuts are tightened after connection. Then, the external cables are laid. The external cables include the second power connection cable and the second communication connection cable. The second power connection cable connects the DC bus terminal in the elevator control cabinet 323 and the first power interface 131 of the power management module 100. The second power connection cable can be fixed along the outer side of the transverse guide rail 301 with a dedicated cable bracket. The bending radius of the second power connection cable is ≥4 times the diameter of the second power connection cable. It avoids moving parts such as the traction machine 320 wire rope and the car 321, and the distance between it and the traction machine 320 power connection cable is ≥300mm to reduce electromagnetic interference and not affect the normal operation of the guide rail lubrication system. The second power connection cable can be a 16mm² flame-retardant copper core cable, cut to the actual spacing with a 200mm redundancy, and protected by a corrugated sheath. The second communication connection cable connects the communication terminal of the elevator control cabinet 323 to the first communication interface 132 of the power management module 100. After connection, use a multimeter to test the insulation resistance between the power management module 100 and the energy storage battery module 200; it should be ≥10MΩ to ensure compliance with electrical safety standards. Connect the grounding terminals of the power management module 100 and the energy storage battery module 200 to the elevator's dedicated grounding electrode via a grounding wire, ensuring a secure connection without any loose connections.

[0095] Interference detection and performance verification are performed in S50, specifically including: interference and load-bearing capacity testing, heat dissipation and electrical performance testing, and safety testing. Interference and load-bearing capacity testing involves starting the elevator under no-load conditions and observing that there is no interference between the modules and the running trajectories of the car 321 and counterweight 322, and that the spacing between the modules and other elevator components meets requirements; checking that all cables are free from pulling and friction, and that the corrugated pipes are undamaged; full-load load-bearing capacity verification is performed: the elevator runs up and down three times under full load, and the deformation of the transverse guide rail 301 is ≤0.5mm, and there is no looseness in the connection between each module and the load-bearing support arm, ensuring the stability of the load-bearing structure. Heat dissipation and electrical performance testing involves simulating the elevator running under full load for 30 minutes, and checking that the surface temperature of each module is ≤50℃ indicates normal heat dissipation; monitoring the elevator energy-saving system through the BCU shows normal operation, stable communication signals between modules, and no electromagnetic interference from the high-voltage circuit causing abnormalities in the low-voltage signals. Safety testing involves simulating a single module failure, disconnecting the quick-plug connector, and verifying that the failed module does not affect the operation of another module or the elevator foundation system, meeting fault isolation requirements.

[0096] Combination Figure 3 and Figure 4 After installation, the power management module 100 and the energy storage battery module 200 are installed side by side with the traction machine 320 on the transverse guide rail 301, making full use of the existing load-bearing space of the transverse guide rail 301 without occupying the side wall space of the shaft 300; the load-bearing structure is stable and reliable, and the deformation of the transverse guide rail 301 is controlled within a safe range; the heat dissipation of each module is uniform, maintenance is convenient, the elevator energy saving rate can reach 20-30%, and all indicators meet safety and energy saving standards, making it suitable for machine room-less scenarios without load-bearing side walls 310.

[0097] Figure 5 and Figure 6 This document illustrates an installation scheme for an elevator energy-saving system in a narrow elevator machine room 310, such as in older buildings or compact elevators with small machine rooms. The machine room 310 has an area of ​​less than 4 square meters, a maintenance passage width of 600mm-800mm, and no ventilation system on the ceiling (summer temperature can reach 40℃). The traction machine 320 is fixed to a support platform on one side of the machine room 310, and the control cabinet 323 is installed on one wall of the machine room 310. The machine room 310 also contains steel cables, speed governors, and other equipment. The space is compact, and there is a risk of temperature rise. Taking an elevator energy-saving system comprising one power management module 100 and two energy storage battery modules 200, all wall-mounted, as an example, the corresponding system also includes a wall-mounted mounting rail assembly. This assembly includes a fixed bracket and a sliding rail, with the fixed bracket being a wall-mounted angle steel bracket and the sliding rail being a wall-mounted sliding rail. The installation method is as follows:

[0098] In S10, the installation area is planned, and the installation area of ​​the power management module 100 is arranged on the first wall where the control cabinet 323 is located, and it is placed adjacent to the control cabinet 323. At the same time, the distance between the power management module 100 and the control cabinet 323 is ≥300mm to facilitate the connection with the DC bus of the control cabinet 323, and a heat dissipation gap is reserved. In addition, the power management module 100 is arranged to avoid the opening range of the control cabinet 323 door. For example, the distance between the power management module 100 and the edge of the cabinet door is ≥200mm. Furthermore, the bottom of the power management module 100 is ≥300mm away from the ground of the machine room 310 to avoid the influence of ground moisture, and the top of the power management module 100 is ≥200mm away from the ceiling of the machine room 310 to ensure unobstructed air intake of the cooling fan. The front of the power management module 100 faces the maintenance passage, and a distance of ≥600mm is reserved for operation space, while not encroaching on the entrance passage of the machine room door 311. The installation area of ​​the energy storage battery module 200 is located on the second wall opposite the machine room door 311, avoiding the running trajectory of the traction machine 320 wire rope, speed limiter and other moving parts; the outer edge of the energy storage battery module 200 is ≥600mm away from the maintenance passage to ensure unobstructed maintenance passage; the bottom of the energy storage battery module 200 is ≥300mm away from the ground to avoid the influence of ground moisture; the top of the energy storage battery module 200 is ≥200mm away from the ceiling to ensure unobstructed air intake of the cooling fan; when multiple energy storage battery modules 200 are arranged horizontally, the spacing between adjacent energy storage battery modules 200 is ≥100mm, and the overall installation range does not exceed the unused area of ​​the second wall.

[0099] S20 is used for the installation of the load-bearing bracket. Specifically, the power management module 100 is installed using a wall-mounted angle steel bracket. The angle steel bracket has a load-bearing capacity of ≥50kg and a safety factor of ≥2 to accommodate the weight and maintenance load of the power management module 100. The angle steel bracket can be fixed to the first wall surface with expansion bolts, and the installation height of the angle steel bracket ensures that the center of the first interface component 130 on the first panel 113 is 1.2m-1.3m from the ground, which is in line with the ergonomic operating height. After installation, the horizontal error of the angle steel bracket is ≤1mm and the vertical error is ≤1mm. The energy storage battery module 200 is installed using a wall-mounted sliding rail. The length of the sliding rail is determined according to the number of energy storage battery modules 200. For example, the length of the sliding rail for a single module is 400mm, and the length of the sliding rail is extended according to the actual number of modules. The rail spacing is 700mm to match the size of the energy storage battery module 200. The load-bearing capacity of the sliding rail is ≥60kg. It is fixed to the second wall with expansion bolts, and the tightening torque of the expansion bolts is 35N·m-40N·m. The installation direction of the sliding rail is parallel to the maintenance channel to ensure that the energy storage battery module 200 slides in and out without obstruction and smoothly without jamming.

[0100] In S30, the installation of each module is carried out. Specifically, a single person uses the first handle 114 to move the power management module 100 to the angle steel bracket, adjusts the position of the power management module 100 so that its back positioning hole is aligned with the bracket hole on the angle steel bracket, and fixes it with bolts to prevent it from falling off; the first interface component 130 of the power management module 100 is arranged facing the control cabinet 323 to shorten the wiring distance; after installation, the verticality error of the power management module 100 is ≤1mm, the power management module 100 is tightly attached to the wall, and the gap is ≤2mm. A single person uses the second handle 215 to slide the energy storage battery module 200 into the installation position along the sliding guide rail, and the second interface component 220 of the energy storage battery module 200 is arranged facing the maintenance channel; when installing multiple modules, each energy storage battery module 200 is slid into the sliding guide rail in sequence, and the distance between adjacent modules is maintained at 100mm. Each module is fixed by the guide rail positioning pin to prevent sliding; the second handle 215 is arranged facing the maintenance channel to facilitate subsequent disassembly and maintenance.

[0101] Electrical connections are made in S40. First, insulated cable trays are laid along the route "Power Management Module 100 → Wall of Equipment Room 310 → Energy Storage Battery Module 200". The insulated cable trays are fixed along the wall of Equipment Room 310 with a fixing point spacing of ≤1.5m. Corner fittings are used at the corners of Equipment Room 310 to avoid cable bending and damage. The distance between the insulated cable trays and the ground is ≥200mm to avoid water accumulation on the ground. The first power connection cable and the first communication connection cable pass through the first and second slots of the insulated cable trays, respectively, to avoid crossing and tangling with cables from other equipment. Then, interface connections are made. The power management module 100 is connected to the energy storage battery module 200 through the first power connection cable and the first communication connection cable. Both ends of the first power connection cable and the first communication connection cable are secured with quick-plug connectors with locking structures. The first communication connection cable can be a shielded twisted pair cable and is laid separately from the first power connection cable to ensure a spacing of ≥50mm. The first communication connection cable can be tightened with a locking nut to prevent loosening. Next, connect the power management module 100 and the DC bus of the elevator control cabinet 323 via an external cable. After the connection is completed, use a multimeter to test the insulation resistance between the power management module 100 and the energy storage battery module 200. The resistance is ≥10MΩ, which meets the electrical safety standards. Connect the grounding terminals of the casings of the power management module 100 and the energy storage battery module 200 to the elevator-specific grounding body through a grounding wire to ensure that the grounding wire is firmly connected and there are no loose connections.

[0102] The S50 underwent channel verification, heat dissipation testing, and performance testing. Channel verification involved measuring the width of the entrance channel at machine room door 311 to be ≥800mm and the maintenance channel width to be 600mm-800mm, ensuring no encroachment by modules or insulated cable trays. The doors of machine room door 311 and control cabinet 323 were opened to verify no collision or interference with the modules. Heat dissipation testing involved activating the heat dissipation components of the energy storage battery module 200 and simulating machine room 310 operating at 40℃ for 1 hour, ensuring the surface temperature of each module was ≤55℃ and the overall temperature rise of machine room 310 was ≤5℃. Emphasis was placed on verifying unobstructed heat dissipation for the energy storage battery module 200 and unobstructed airflow from the cooling fan. Performance testing involved testing the regenerative energy recovery efficiency of the elevator energy-saving system to be ≥80% and ensuring stable communication signals between modules. The anti-interference performance of external cables was verified to ensure no signal interference between the elevator energy-saving system and the original elevator control system during elevator operation, complying with relevant safety and energy-saving standards.

[0103] After final installation, it can make full use of the scattered space on both sides of the computer room 310, adapt to the layout of the narrow computer room 310, and does not encroach on the ground space and maintenance passage; the thermal performance is significantly optimized, and the modules are easy to disassemble and install individually; the elevator power saving rate can reach 20%-30%, and the cables have strong anti-interference ability, the system operates stably, and it is suitable for the installation and use needs of such narrow computer rooms 310.
