Abstract
Description
Technical Field
[0001] This utility model belongs to the field of railway station fire protection engineering, specifically relating to a new energy integrated thermal insulation fire protection system. Background Technology
[0002] With the advancement of urbanization, railway trains are becoming increasingly ubiquitous, making the construction of fire protection facilities at railway stations particularly important. Fire pump rooms and fire water tanks, as water storage facilities, are indispensable for railway stations.
[0003] Traditional fire pump rooms and fire water tanks are mostly underground structures to ensure water temperature and prevent the effects of winter freeze-thaw cycles, with fire water tanks typically located below the frost depth. Furthermore, the self-priming nature of fire pumps dictates that the depth of the fire pump room cannot exceed the bottom of the fire water tank. Therefore, the underground portions of fire water tanks and fire pump rooms are quite deep, requiring significant excavation. However, excavation conditions in some station areas are limited, resulting in high construction requirements and costs. Therefore, designing a new type of fire water tank and fire pump room structure is essential. Utility Model Content
[0004] The purpose of this utility model is to provide a new energy integrated thermal insulation fire protection system to solve the problems of limited excavation conditions in some underground areas of stations or insufficient thermal insulation in above-ground construction in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A new energy integrated thermal insulation fire protection system includes a fire water tank. The main body of the fire water tank is a quadrangular prism, and the top is a quadrangular pyramid, covered with thermal insulation material. The lower half of the main body is located underground. A fire pump room is set on one side of the fire water tank, and a heat collection control and management room is set on the other side. A flat plate heat collector is installed on the top outer surface of the side where the heat collection control and management room is located, and photovoltaic modules are installed on the remaining top outer surface.
[0007] Furthermore, a fire pump is installed inside the fire pump room, and the fire pump is connected to a fire pump supply pipe and a fire pump suction pipe. The other end of the fire pump suction pipe is located in the fire water tank.
[0008] Furthermore, a heat collection box is provided inside the heat collection control and management compartment, and the flat plate heat collector is connected to the heat collection box through a lower circulation pipe and an upper circulation pipe for the heat collection medium.
[0009] Furthermore, a radiator is installed on the partition wall between the heat collection control management compartment and the fire water tank, located inside the fire water tank. The heat collection box and the radiator are connected by a heat supply medium return pipe and a heat supply medium outflow pipe.
[0010] Furthermore, a heat collection medium circulation pump is connected to the upper circulation pipe of the heat collection medium, and a heat supply medium circulation pump is connected to the lower outlet pipe of the heat supply medium.
[0011] Furthermore, the heat collection control and management chamber is equipped with an inverter and an energy storage device, which are connected to the heat collection medium circulation pump and the heat supply medium circulation pump through the circulation pump power supply line.
[0012] Furthermore, the fire water tank is connected to a fire water tank replenishment pipe and is also provided with a fire water tank inspection hole. A control box is installed inside the solar collector control management compartment. The control box is connected to the photovoltaic modules and is used for temperature control.
[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0014] This utility model provides a new energy integrated insulation fire protection system that significantly reduces the amount of earthwork excavation during the construction of fire water tanks. The top is shaped like a regular square pyramid, the outer wall of the tank is insulated, and photovoltaic modules are installed on the surface. Through a heat exchange system, the internal temperature of the tank is maintained, preventing freezing at low temperatures. This not only reduces the construction difficulty and cost of underground fire water tanks but also achieves energy conservation and environmental protection by utilizing green energy. The increased tank depth also reduces the head of the fire pump, thereby reducing energy consumption and facilitating pump installation and maintenance.
[0015] In addition, the fire water tank, after being covered with insulation material, can also serve as a good heat storage device. At the same time, it can be equipped with an external energy storage device and a heating system to ensure the temperature inside the tank during rainy weather. It is not limited by weather or low altitude. The combination of new energy technology and traditional technology makes it applicable to a wide range of scenarios. Attached Figure Description

The lower half of the main body is underground, while the top and the upper half of the main body are above ground. The underground depth is 3 meters, and the above-ground depth is calculated based on fire protection requirements. A flat-plate solar collector 7 is installed on the outer surface of the top of the quadrangular pyramid on the side where the thermal control and management compartment 21 is located, and photovoltaic modules 2 are installed on the remaining outer surfaces.

The flat-plate solar collector 7 is connected to the solar collector box 11 via a lower circulation pipe 9 and an upper circulation pipe 10 for the solar collector medium. A solar collector medium circulation pump 12 is connected to the upper circulation pipe 10. A radiator 15 is installed inside the fire water tank 1 on the partition wall between the solar collector control and management compartment 21 and the fire water tank 1. The solar collector box 11 and the radiator 15 are connected via a heating medium return pipe 8 and a heating medium outlet pipe 13. A heating medium circulation pump 14 is connected to the heating medium outlet pipe 13.

The fire water tank supply pipe 19 is connected to the fire water tank 1 through the fire water tank inspection hole 18. The fire water tank in the fire water tank compartment 1 provides a water source for the fire protection system, and the fire pump suction pipe 6 in the fire pump room compartment 3 supplies water to the fire pump 4, which provides the required pressure and flow to the fire protection system through the fire pump supply pipe 5.
