[0002] Shallow geothermal energy is a renewable green energy source with rich reserves, wide distribution, stability and reliability. Based on the continuous development and utilization of shallow energy, various water source heat pump technologies have developed rapidly. The water source heat pump heating and cooling system has the characteristics of higher efficiency, more energy conservation and lower carbon environmental protection. To make full use of the water source heat pump system, promote the sustainable high-quality development of shallow energy utilization, make it play a more important role in the energy production and consumption revolution, improve the utilization efficiency of renewable energy, and effectively improve the project environment. At present, coastal public buildings and the converter station platforms of deep-sea and far-sea offshore wind farms are all using more energy-efficient water source heat pumps as the air-conditioning cold and heat sources, as well as the indirect cooling water for the electrical equipment on deep-sea and far-sea platforms.

[0003] To utilize shallow water sources (rivers, lakes, seas), there are various water intake methods. Currently, most of them are to build pump houses and water intakes. For example, Chinese patent document CN209468808U, publication (announcement) date: October 8, 2019, discloses a caisson-type seawater intake system, which includes multiple groups of caisson foundations. A water intake platform is fixed on the caisson foundation. Below some of the water intake platforms, there is a caisson pump house placed on the caisson foundation. A long-shaft seawater pump is installed in the caisson pump house. The water intake of the long-shaft seawater pump is sunk below the lowest water level. The bottom of the caisson pump house is provided with a water inlet. A plank road is connected between two adjacent water intake platforms. Below the water intake platform and the plank road, there is a conveying pipeline connecting the long-shaft seawater pump and the seawater user. Its characteristics are: in this document, the long-shaft seawater pump is installed on the seabed through the caisson pump house, and the water intake of the long-shaft seawater pump is installed below the lowest water level of the water intake point, which can ensure stable, reliable and uninterrupted supply of enough seawater to seawater users even at the lowest tide of the sea; its disadvantages are: when installing the water intake system, it is necessary to install a caisson foundation at the bottom of the water source, and then install a caisson pump house on the caisson foundation, with a relatively complex structure and inconvenient installation.
