Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and relates to a photovoltaic power generation heating system for fire pump stations in cold regions. Background Technology

[0002] Traditional heating systems in China mostly use coal-fired, gas-fired, or oil-fired boilers as heat sources, connected to end users through pipe networks. These traditional systems have numerous drawbacks, affecting efficiency, environmental friendliness, and economy. They emit large amounts of smoke, sulfur dioxide, nitrogen oxides, and other harmful substances, severely polluting the atmosphere. They also suffer from high transportation costs, low combustion efficiency, high operating expenses, and safety hazards.

[0003] Air source heat pump heating: The heating characteristic curve does not match the building's required heating characteristic curve, making it unable to adapt to extreme weather conditions. Furthermore, the compressor operates under high pressure ratio conditions for extended periods, increasing the failure rate. Ground source heat pump heating: High initial installation costs, complex systems, difficult installation, small heating range, and prone to cold accumulation. In cold regions, energy consumption and carbon emissions from traditional coal-fired heating remain consistently high. Replacing coal-fired heating with low-carbon electricity is undoubtedly an effective energy-saving and carbon-reducing measure. However, electric heating suffers from high operating costs and high power consumption, hindering its widespread application. Strengthening the combined application of solar and conventional energy sources to significantly improve low-carbon energy heating capacity and reduce the scale of traditional heat source construction is undoubtedly a solution.

[0004] Above-ground fire pump stations in cold regions include fire pump rooms and fire water tanks. The temperature inside the pump room must not be lower than 5°C, and the fire-fighting water in the fire water tank must not freeze. In areas with a heating network, radiators are used for heating; in areas without a heat source, electric heaters are used. The former fails to meet energy conservation and emission reduction requirements, and electric heating consumes a lot of electricity, resulting in poor long-term economic viability. In cold regions, measures must be taken to ensure that the fire-fighting water in the fire water tank does not freeze in winter. When there is no industrial waste heat available, electric heat tracing is usually used to insulate the tank. However, electric insulation suffers from high electricity consumption, high operating costs, and unreliable maintenance. Finding more reasonable, energy-efficient, and economical insulation measures for above-ground fire water tanks is an urgent problem to be solved. Summary of the Invention

[0005] This invention provides a photovoltaic power generation heating system suitable for fire pump stations in cold regions, which solves the antifreeze and heating needs of fire pump stations and water tanks in cold regions, and achieves low-carbon, low-consumption and high-reliability operation.

[0006] The specific technical solution is as follows:

[0007] This utility model provides a photovoltaic power generation heating system suitable for fire pump stations in cold regions, including: a rooftop photovoltaic power generation unit, including an adjustable tilt bracket and a solar panel array; an electric heating film module for the inner wall of the pump room and an electric heating film module for the outer wall of the fire water tank, both of which are powered by DC; and an intelligent control system, including a temperature sensor, a power management module and an energy storage unit.

[0008] Furthermore, the electrothermal film has a flexible and bendable structure with quick-installation clips on its edges.

[0009] Furthermore, the energy storage unit has a reserved wind power generation access port to support wind-solar hybrid energy input.

[0010] Furthermore, the pump room interior wall electric heating film module has a multi-layer structure, consisting of a first insulation layer, a first electric heating film, a gypsum board, and a surface coating layer, arranged sequentially from the inside out.

[0011] Furthermore, the electric heating film module on the outer wall of the fire water tank has a multi-layer structure, consisting of a second electric heating film, a second insulation layer, and a waterproof sealing layer, arranged sequentially from the inside out.

[0012] Furthermore, the house power management module includes a combiner box, a rectifier, and a solar charge / discharge controller. The combiner box is connected to the solar panel and is used to collect DC power and transmit it to the rectifier. The rectifier is connected to the solar charge / discharge controller, and the solar charge / discharge controller is connected to the energy storage unit.

[0013] Furthermore, the temperature sensor is installed inside the electric heating film module on the inner wall of the pump room and inside the electric heating film module on the outer wall of the fire water tank.

[0014] Furthermore, the energy storage unit includes a lithium battery pack.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Solar energy is a renewable energy source that generates no pollutants during power generation. Its distributed nature allows for local development and use, reducing the burden of energy transmission and avoiding the geographical limitations and security risks associated with traditional energy supplies. Photovoltaic DC direct-fired electric heating film reduces energy conversion losses, improving overall energy efficiency by over 20%. Intelligent temperature control and energy storage design provide the system with 72 hours of self-sufficiency, adapting to extreme weather conditions. Modular electric heating film components support rapid replacement, reducing maintenance costs by 30%. Annual operating costs are 60% lower than traditional electric heating, and carbon emissions are reduced by 90%. Attached Figure Description
