Specifically, it relates to a skid-mounted system for a fire pump station used in energy supply stations for fire protection. Background Art

[0002] In recent years, with the increasing number of new energy vehicle users, the construction of comprehensive energy supply stations such as refueling, gas filling, hydrogen refueling, charging, and battery swapping has entered a stage of rapid development. Since the project construction sites are mostly located in urban built-up areas, the project has high requirements for fire protection.

[0003] For comprehensive energy supply stations such as refueling, gas filling, hydrogen refueling, charging, and battery swapping, according to standards and specifications such as "Technical Standard for Motor Vehicle Fueling, Gas Filling, and Hydrogen Refueling Stations", "Technical Specification for Hydrogen Refueling Stations", and "Battery Swapping Station for Battery-Swapping Heavy Trucks", a fire protection system should be set up. The fire protection system consists of multiple functional modules such as a water storage system, a fire pump pressurization system, an automatic water replenishment system, a heat tracing and insulation system, a supporting pipeline system, and a skid-mounted container system. However, through research on the fire protection system in energy supply stations, it is found that the following problems generally exist: it involves multiple specialties such as machinery, electricity, instrumentation, telecommunications, piping, and water supply and drainage, and the design work process is long; the pipe system structure of the fire water supply and pressurization system is loose, the floor area is large, and the reuse rate of pipeline layout design and equipment is low; the number of pipe fittings and instrumentation parts is small but the variety is large, and the procurement is cumbersome; the construction involves dangerous and major projects, the expert demonstration period is long, and the construction environmental protection pressure is high. The control cabinets and inspection cabinets corresponding to the pump sets need to be placed in a clean environment, far from the pump body, and the cables such as fire protection signals need to be laid over a long distance. Summary of the Utility Model

[0004] In order to solve the technical problems of long design process, cumbersome procurement, long construction period, and high environmental protection pressure existing in the prior art, the utility model provides a skid-mounted system for a fire pump station used in energy supply stations.

[0005] A pump station skid-mounted system for a refueling station's fire protection provided by the present utility model includes a water storage system, a fire pump pressurization system, an automatic water replenishment system, a supporting pipeline system, and a container system. Each system is a functional module that realizes a specific function; the water storage system is a concrete water tank or a fire protection water tank; the fire pump pressurization system includes a fire pump, a fire inspection cabinet, and a fire control cabinet; the automatic water replenishment system includes a pressure gauge, a flow meter, a liquid level gauge, a control valve, and a corresponding control system; the supporting pipeline system includes a series of pipe systems and control valve groups that connect the water storage system, the fire pump pressurization system, and the automatic water replenishment system, and is a passage for realizing water replenishment of the water storage system and pressurizing and delivering water by the fire pump; the container system includes a container body and supporting pipelines provided on the container body and communicating with the outside; each system is connected through the corresponding supporting pipeline system; the fire pump pressurization system, the automatic water replenishment system, and the supporting pipeline system are integrally assembled in the container body of the container system to form a relatively independent container skid, and this container skid is communicated with the water storage system through the supporting pipelines on the container body.

[0006] The water storage system can be set in different forms such as underground, semi-underground, and above-ground according to the site conditions. According to the different grade requirements of the refueling station, the fire protection water storage flow in the station is different, and a concrete water tank or a fire protection water tank can be used; the fire protection water tank can be a carbon steel tank or a fiberglass tank. To reduce major hazardous projects on site, the burial depth of the underground water storage system is controlled within 5.0 m. A remote transmission liquid level gauge is equipped in the water storage system, and the liquid level gauge has high and low liquid level alarm functions, and the fire pump is interlocked to stop while the low-low liquid level alarm is given; the water storage system can be provided with a return port, and the fire protection waste water after interception flows through the return port during an accident state and is recycled to the water storage system to realize the recycling of fire protection water and save water resources.

[0007] The fire pump pressurization system starts the fire pump through the fire inspection cabinet or manually to pressurize the fire protection water to the fire water pipe network; the fire pump is equipped with a fire control cabinet, which receives the fire alarm signal, transmits the running state of the pump to the upper-level PLC or DCS system, and receives the control signal issued by the upper-level PLC or DCS system to realize the on-site or remote start and stop of the fire pump and the interlock function.

[0008] The automatic water replenishment system realizes the automatic water replenishment of the water storage system through its pressure gauge, flow meter, liquid level gauge, and control valve. The control valve adopts a gate valve, a check valve, a float valve, etc. The skid-mounted system takes water from the system production water supply pipe or the domestic water supply pipe and supplies it to the water storage system. The water storage system is provided with a control valve, and the control valve opens for automatic water replenishment when the liquid level is low, and closes after reaching the set liquid level.

[0009] As an improvement, the skid-mounted pump station system for fire protection at the energy refueling station can also be equipped with a heat preservation and tracing system. In areas with freezing seasons, the pipelines, valves, and fire pumps above ground can be prevented from freezing during the freezing period through the installation of a heat preservation and tracing system, which may affect the normal operation of the fire protection system. The heat preservation and tracing system can be electric tracing, steam tracing, or air-conditioning heating; for the facilities located inside the container skid, they can also be heated and protected from freezing through the air-conditioning system.

[0010] The skid-mounted pump station system for fire protection at the energy refueling station can be applied to one or more scenarios such as LNG stations, LPG stations, hydrogen refueling stations, or combined refueling, gas filling, hydrogen refueling, charging, and battery swapping stations.

[0011] The utility model has the following beneficial effects:

[0014] 3) The assembled skid-mounted pump station system for fire protection at the energy refueling station, with the internal liquid level control system, automatic water replenishment system, and recycled water system, meets the fire protection requirements of the energy refueling station, reduces the volume of fire protection water stored in the station, and is very helpful for reducing the overall investment of the energy refueling station.

[0015] The utility model optimizes and combines the configuration of the fire protection functional system at the energy refueling station to form an integrated, standard, and enclosed skid-mounted fire pump station system, which can reduce the floor area occupied by the fire protection system, reduce cable laying, reduce the investment in the fire protection system inside the comprehensive energy refueling station, achieve modular construction, and eliminate major hazardous projects on-site. It has the advantages of a compact structure, a single source of assembled goods, a short procurement cycle, low installation and maintenance costs, convenient maintenance, and a modular structure, which is very beneficial for reducing the floor area, construction costs, and construction cycle.
