Description
Technical Field
[0001] This utility model belongs to the technical field of railway water supply systems, and relates to a pumping station, specifically a prefabricated intelligent pumping station that integrates railway domestic water supply and fire-fighting water supply functions. Background Technology
[0002] The railway system is densely populated and has complex equipment. In the event of a fire or water supply interruption, it may cause a major safety accident, requiring a rapid response from the fire protection system and a continuous and stable operation of the water supply system.
[0003] Railway stations are mostly located in densely populated urban areas where land resources are scarce. Traditional separate domestic and fire pump stations occupy a large amount of space and require independent construction, resulting in high investment costs. The environments along railway lines are complex (such as mountainous areas, cold regions, and earthquake zones), requiring equipment to possess vibration resistance and corrosion resistance characteristics. Traditional pump stations struggle to meet these diverse environmental requirements. Furthermore, the wide distribution of railway stations necessitates decentralized maintenance of conventional pump stations, leading to high costs for manual inspections and low fault response efficiency.
[0004] In the aforementioned traditional solutions, domestic pumping stations and fire pumping stations are constructed independently, resulting in redundant equipment investment, redundant pipeline systems, decentralized control, and low energy and space utilization. Fire pump sets rely on external water sources or separate water tanks, and when a fire occurs, they need to wait for the water tank to fill up or the pipeline pressure to build up, delaying the opportunity to extinguish the fire (the response time often exceeds 30 seconds). Traditional pumping stations require on-site pouring and customized installation, resulting in a long construction period, and subsequent expansion or maintenance requires the system to be shut down, affecting the normal operation of the railway.
[0005] The construction of "smart railways" requires infrastructure to be upgraded towards modularization, digitalization, and energy conservation. The railway system needs to reduce energy waste and carbon emissions, and the high energy consumption of traditional pumping stations urgently needs to be addressed. Furthermore, regulations such as the "Railway Fire Safety Management Measures" require that station fire protection systems must have rapid start-up and continuous water supply capabilities, which existing solutions cannot fully meet. Summary of the Invention
[0006] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a prefabricated intelligent integrated pump station for railway systems that integrates domestic and fire protection functions.
[0007] To achieve the above objectives, the technical solution of this utility model is as follows:
[0008] This prefabricated intelligent integrated pump station, used in railway systems, integrates domestic and fire protection functions. The integrated pump station is located at railway stations and includes a fire pump room, a domestic pump room, a fire water tank, and a domestic water tank. These four components share a single pump station foundation and are assembled from multiple metal modular panels using bolts. The fire pump room and domestic pump room are adjacent to each other. The fire water tank is located outside the fire pump room. The domestic water tank is located inside or outside the domestic pump room. The fire pump room includes a fire control cabinet and a complete set of IoT fire-fighting units, which are connected to the fire control cabinet, the fire water tank, and the external fire protection system mains. The domestic pump room includes a domestic water control cabinet and constant pressure variable frequency water supply equipment, which is connected to the domestic water control cabinet, the domestic water tank, and the external domestic water supply network.
[0009] Furthermore, the integrated pump station is configured as either above ground or underground.
[0010] Furthermore, the constant pressure variable frequency water supply equipment is equipped with multiple sets of parallel water pumps and connecting pipelines.
[0011] Furthermore, the complete set of IoT fire-fighting units is skid-mounted and prefabricated in the factory before transportation as a whole.
[0012] Furthermore, the metal module plate is configured as an X-shaped tie-rib module plate or an arc-rib type module plate.
[0013] Furthermore, both the fire water tank and the domestic water tank are equipped with a water inlet and at least two vent pipes on their tops. Both the fire water tank and the domestic water tank are equipped with overflow and venting pipes and level gauges on their exteriors.
[0014] Furthermore, each of the fire pump room and the domestic pump room is equipped with at least two mechanical ventilation devices on its roof; each of the fire pump room and the domestic pump room is equipped with a dehumidifier and two sewage pumps, one in use and one on standby.
[0015] Furthermore, both the fire pump room and the domestic pump room are equipped with pump room doors.
[0016] Furthermore, the pump station foundation includes a concrete cushion layer and reinforced concrete arranged sequentially from bottom to top.
[0017] The improvements of this utility model include:
[0018] (1) Integrated design to achieve efficient resource integration and optimized space utilization.
[0019] By integrating domestic water supply and fire-fighting water supply into a single design, the barriers of traditional independent systems are broken down, and the foundation of the pump station is shared, reducing equipment redundancy and land occupation. Moreover, the modular design achieves "dual system integration," solving the problem of resource waste caused by repeated construction of traditional railway stations and reducing initial construction costs.
[0020] (2) Optimize the workload and shorten the construction period
[0021] Adopting a standardized modular design (size error ≤3mm), the assembly technology transforms on-site construction into factory prefabrication, eliminating the risk of uncontrollable construction cycle caused by complex geographical environment in railway engineering, and is particularly suitable for railway stations with special geological conditions such as plateau and permafrost.
[0022] (3) Reduced maintenance costs
[0023] Unified management and maintenance reduce the number of devices and the frequency of personnel inspections, thus reducing long-term operation and maintenance costs (integrated design reduces the number of devices, and personnel only need to inspect a single system, reducing working hours and labor costs).
[0024] (4) Green energy-saving benefits
[0025] By utilizing energy efficiency optimization and resource recycling technologies, we respond to the green development requirements of "dual carbon" for transportation infrastructure, which aligns with the "dual carbon" goals and the development direction of smart cities.
[0026] Advantages of this utility model:
[0027] This utility model achieves reduced space occupation and shorter construction period through the integrated design of domestic water supply and fire-fighting water supply systems; the integration of domestic and fire-fighting systems reduces energy consumption; the modular assembly structure is adaptable to complex environments such as plateaus and permafrost, reducing the overall life-cycle operation and maintenance costs; unified management and maintenance reduce the number of equipment and the frequency of personnel inspections, thus reducing long-term operation and maintenance costs; and the adoption of a fully bolted assembly structure simultaneously resolves the contradiction between water supply reliability, emergency efficiency, and low-carbon economy in railway scenarios. This utility model achieves multiple goals: efficient space utilization, significant cost reduction, improved safety performance, and optimized energy consumption management.

Detailed Implementation
[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0033] Reference Figures 1 to 3 As shown, the prefabricated intelligent integrated pump station for railway systems, which integrates domestic and fire protection, includes a fire pump room 1, a domestic pump room 2, a fire water tank 3, and a domestic water tank 4, all of which share a reinforced concrete pump station foundation.
[0034] The fire pump room 1 and the domestic pump room 2 are located adjacent to each other.
[0035] Both fire pump room 1 and domestic pump room 2 are bolt-assembled pump rooms, which means that multiple metal module panels are connected and fixed together by bolts, saving time and effort.
[0036] The metal module plate can be configured as a prefabricated stainless steel water tank high-rigidity molded module (see Chinese Patent CN201521118103.4 for details), or an assembled water tank molded plate (X-shaped tie rod) (see Chinese Patent CN201530269231.8 for details), or an ultra-rigid bidirectional corrugated module (see Chinese Patent CN202123151217.7 for details, etc.).
[0037] The fire pump room 1 is equipped with a fire control cabinet 12, which is connected to the external fire protection system, the complete set of Internet of Things fire-fighting units 5, the fire pump room mechanical ventilation device 7, the fire pump room dehumidifier 11, and the fire pump room sewage pump 13.
[0038] A complete set of IoT-enabled fire-fighting units 5 (an existing product, not described in detail here) is installed in fire pump room 1. During construction, the complete set of IoT-enabled fire-fighting units 5 is connected to the pre-embedded pipe of the suction trough of fire water tank 3 and the main pipe of the external fire protection system. When a fire occurs, upon receiving signals from pressure switches, flow switches, or alarm valve group pressure switches installed on the main pipe of the fire protection system it serves, the complete set of IoT-enabled fire-fighting units 5 immediately starts and activates the fire-fighting mode to extinguish the fire through fire control cabinet 12.
[0039] Preferably, the complete set of IoT fire-fighting unit 5 adopts an overall skid-mounted design, which is prefabricated in the factory and transported as a whole.
[0040] At least two mechanical ventilation devices 7 are installed on the top of the fire pump room 1 for air exchange in the pump room. The mechanical ventilation device is a cap-shaped ventilation device with an axial flow fan inside (for details, see Chinese Patent ZL202320213870.1).
[0041] A fire pump room dehumidifier 11 is installed in the fire pump room 1. The dehumidifier is linked with the fire pump room mechanical ventilation device 7 to automatically control the humidity and air exchange rate of the pump room, thus ensuring the safety of the control system and the stability of the motor operation.
[0042] Two sewage pumps 13 are installed in fire pump room 1 for daily drainage, one in use and one on standby, serving as backups for each other.
[0043] Fire pump room 1 shall be equipped with a pump room door of not less than 2m*2m.
[0044] The fire water tank 3 is located outside the fire pump room 1 and adjacent to the fire pump room 1.
[0045] The fire water tank 3 is a bolt-assembled structure, meaning that multiple metal module plates are connected and fixed together by bolts, saving time and effort. The metal module plates can be configured as a type of prefabricated stainless steel water tank high-rigidity molded module (see Chinese Patent CN201521118103.4 for details), or an assembled water tank molded plate (X-shaped tie rod) (see Chinese Patent CN201530269231.8 for details), or an ultra-rigid bidirectional corrugated module (see Chinese Patent CN202123151217.7 for details, etc.).
[0046] The top of the fire water tank 3 is equipped with a fire water tank inlet 14 and a fire water tank vent pipe 8 (at least two, one above the other). The outside of the fire water tank 3 is equipped with an overflow 15, a vent pipe 16, and a level gauge 17. Figure 1 and Figure 2 (As shown).
[0047] The domestic pump room 2 is equipped with a domestic control cabinet 18, which is connected to the domestic constant pressure variable frequency water supply equipment 6, the domestic pump room mechanical ventilation device 9, the domestic pump room dehumidifier 19, and the domestic pump room sewage pump 20.
[0048] A constant-pressure variable-frequency water supply system 6 is installed in the domestic water pump room 2. This system is connected to both the external domestic water supply network (tap water pipe) and the domestic water tank 4. The system uses pressure sensors to monitor the pressure of the network (external domestic water supply network) in real time. The PLC in the domestic water control cabinet 18 automatically adjusts the speed of the pump motors in the system 6 to stabilize the water pressure. Simultaneously, the system intelligently switches the number of pumps operating based on water consumption, significantly reducing energy consumption while ensuring continuous water supply.
[0049] At least two mechanical ventilation devices 9 are installed on the top of the domestic pump room 2 for air exchange in the pump room, with the same function as the mechanical exhaust device 7 of the fire pump room.
[0050] A dehumidifier 19 is installed in the domestic pump room 2, with the same function as the dehumidifier 11 in the fire pump room.
[0051] Two sewage pumps 20 are installed in the domestic pumping station 2 for daily drainage, one in use and one on standby, serving as backups for each other.
[0052] The domestic pumping station 2 shall be equipped with a pumping station door of not less than 2m*2m.
[0053] In this embodiment, the domestic water tank 4 is installed inside the domestic water pump room 2 (e.g., Figure 1 As shown in the figure, because the requirements for drinking water are relatively high, when the volume of the domestic water tank 4 is not large, it is usually placed inside the domestic pump room 2 to ensure water quality.
[0054] Alternatively, if the domestic water tank 4 is large in volume, it would take up a lot of space inside the domestic pump room 2. In this case, the domestic water tank 4 would be placed outside the domestic pump room 2 and placed adjacent to it.
[0055] The domestic water tank 4 features a bolt-assembled structure, where multiple metal module panels are connected and fixed together using bolts, saving time and effort. The metal module panels can be configured as a high-rigidity prefabricated stainless steel water tank module (see Chinese Patent CN201521118103.4 for details), or as a prefabricated water tank plate (X-shaped tie rod) (see Chinese Patent CN201530269231.8 for details), or as an ultra-rigid bidirectional corrugated module (see Chinese Patent CN202123151217.7, etc.).
[0056] The top of the domestic water tank 4 is equipped with a domestic water tank inlet 21 and a domestic water tank vent pipe 10 (at least two are installed, one at the top and one at the bottom). The outside of the water tank is equipped with an overflow and venting pipe and a level gauge.
[0057] Furthermore, the prefabricated intelligent integrated pump station for integrated domestic and fire protection in the railway system of this embodiment can be either above ground or underground.
[0058] When the prefabricated intelligent integrated pump station for the integrated domestic and fire protection of the railway system in this embodiment is set as an above-ground pump station, the pump room doors of the fire pump room 1 and the domestic pump room 2 are side-opening doors.
[0059] When the prefabricated intelligent integrated pump station for the railway system in this embodiment is set as an underground pump station, the pump room doors of the fire pump room 1 and the domestic pump room 2 adopt the top-entry door.
[0060] The above description is merely a preferred embodiment of the present utility model and does not constitute a limitation on the scope of protection of the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the scope of protection of the claims of the present utility model.
