Community residents can park their vehicles at the vehicle entrance 9, and the vehicles are automatically transferred to the vacant parking board 3 located at the parking space 13 through the vehicle transfer mechanism, ready for parking and access. During the vehicle extraction process, vehicles in different parking spaces can be exchanged through the vehicle conveying mechanism 12, so that the vehicles can be smoothly released from the garage. And because the shaft parking garage 7 is directly located in the community geothermal energy storage center 4, there is no need to build an additional channel to connect the shaft parking garage 7. The entire vertical shaft parking garage 7 based on the geothermal collection well can effectively utilize the underground space, facilitate residents to park their cars, and save ground space. Compared with traditional underground garages, the vertical shaft parking garage 7 disclosed in the present invention can provide more parking spaces in the limited underground space of urban communities.

The heat exchange circulation loop extends to the community geothermal energy storage center 4. The heat exchange circulation loop is filled with a first heat exchange medium. In order to reduce the use cost, the first heat exchange medium is preferably water, and the heat exchange circulation loop is connected to a first circulation pump that drives the first heat exchange medium to flow back and forth. The first circulation pump continuously circulates the first heat exchange medium in the heat exchange circulation loop, continuously exchanges geothermal energy, and stores geothermal energy in the first heat exchange medium; the energy storage mechanism is arranged in the community geothermal energy storage center 4, and stores a second heat exchange medium for storing geothermal energy. The energy storage mechanism is connected in parallel with a plurality of heat supply circulation pipes 6, and each heat supply circulation pipe 6 is respectively connected to the corresponding heat supply mechanism in the community, so as to supply the second heat exchange medium stored in the energy storage mechanism to the heat supply mechanism through the heat supply circulation pipe 6, thereby ensuring the demand for geothermal energy by the heat supply mechanism. Preferably, the energy storage mechanism includes an energy storage tank 10, in which a second heat exchange medium for energy storage is stored. To reduce the use cost, the second heat exchange medium is preferably water; the outlet of the energy storage tank 10 is connected in parallel with a plurality of heat supply circulation pipes 6. Preferably, the mechanism to be heated is a community building 5, so that the geothermal energy stored in the energy storage mechanism can be supplied to the community building 5 for use.

[0023] The energy storage and heating system based on the smart energy parking garage in the urban community disclosed in the present invention makes full use of the community's underground space to build more parking spaces, saves additional underground space land resources, and provides more convenience for residents to store and retrieve cars. The first heat exchange medium in the heat exchange circulation loop is used to exchange geothermal energy, and a community geothermal energy storage center 4 is established above the shaft garage. The energy storage mechanism in the community geothermal energy storage center 4 is used for heat exchange with the heat exchange circulation loop to complete the storage of geothermal energy, and the energy storage mechanism is connected to the heating mechanism to be supplied through the heating circulation pipeline 6 to provide heat energy to the heating mechanism to be supplied. Geothermal energy is used as the entire energy source for community life, without the need for additional energy transportation and storage costs, reducing the use of traditional energy in urban communities, and can effectively reduce carbon emissions and achieve the community's "zero carbon" life goals.

[0024] In a specific embodiment, a vehicle dispatching mechanism 8 is provided in the community geothermal energy storage center 4. The vehicle dispatching mechanism 8 is used to check the parking situation in the shaft parking garage 7, such as the number of parked vehicles and the remaining parking spaces, and is electrically connected to the vehicle conveying mechanism 12 and the vehicle transfer mechanism. Through the vehicle dispatching mechanism 8, the vehicle conveying mechanism 12 and the vehicle transfer mechanism are electrically controlled to realize fully automatic transmission of vehicles into the garage, which is convenient for residents to store and retrieve vehicles and provides more convenience for residents.

[0025] In a specific embodiment, an energy dispatching mechanism is provided in the community geothermal energy storage center 4. The energy dispatching mechanism is equipped with a temperature sensor installed at the heating mechanism to be supplied and a second circulating pump installed on the heating circulation pipeline 6. The energy dispatching mechanism is electrically connected to the temperature sensor and the second circulating pump. In order to accurately control the heat energy required at the heating mechanism to be supplied, for example, when the heating mechanism to be supplied is a community building 5, residents can call up geothermal energy through the energy dispatching mechanism according to demand, accurately control the geothermal energy to be delivered to the residents' homes, improve the living environment, and form a constant temperature room. Further, the energy dispatching mechanism includes a data acquisition and monitoring module, an energy purchase module, a user interface and a reporting module. The data acquisition module can detect the temperature of the water body storing geothermal energy, thereby monitoring the storage of geothermal energy in real time and ensuring the circulation of geothermal energy exchange. Users can purchase the stored geothermal energy through the user interface of the community geothermal energy storage center 4. At the same time, the purchase situation and storage quantity will be reported to the background in real time, thereby ensuring the effective circulation and replenishment of geothermal energy and ensuring sufficient energy in the community.

[0026] In a specific embodiment, a heat pump mechanism is provided in the community geothermal energy storage center 4, and a second heat exchange medium circulates in the heat pump mechanism. In order to improve the efficiency of geothermal energy extraction, the preferred second heat exchange medium is Freon or heat exchange mediums such as R22, R417A and 134A; a first heat exchanger for heat exchange between the heat pump mechanism and the heat exchange circulation loop is provided, and a second heat exchanger for heat exchange between the heat pump mechanism and the energy storage mechanism is provided. The first heat exchange medium is circulated by using the heat exchange circulation loop to exchange the geothermal energy resources in the geothermal collection well, and the exchanged geothermal energy resources are extracted by using the heat pump mechanism and stored in the energy storage mechanism. It should be noted that according to the different demands for geothermal energy in different seasons, such as taking heat or taking cold, the condenser and evaporator of the heat pump mechanism are switched to exchange heat with the energy storage mechanism through the second heat exchanger, and the evaporator and condenser of the corresponding heat pump mechanism are switched to exchange heat with the heat exchange circulation loop through the first heat exchanger.

[0027] In a specific embodiment, the energy storage mechanism is equipped with a geothermal conversion mechanism 11, which includes a gas circulation pipeline 20 for heat exchange with the energy storage mechanism, and heat exchange gas, such as water vapor, circulates in the gas circulation pipeline 20. The gas circulation pipeline 20 includes a cooling section and a vertically extending working section. A turbine 17 that rotates with the flow of gas is provided at the top position of the working section. The turbine 17 is connected to a generator in a transmission manner. The generator is used to be connected to the power distribution equipment in the community. A cooler 18 for cooling the gas is provided at the cooling section. The geothermal conversion mechanism 11 is used to convert geothermal energy into electrical energy. Specifically, the heat energy of the high-temperature second heat exchange medium in the energy storage mechanism is used to heat the heat exchange gas in the gas circulation pipeline 20, thereby promoting the heat exchange gas to move upward in the vertical direction, so as to drive the turbine 17 to rotate, thereby converting the geothermal energy into mechanical energy, and the turbine 17 rotates to do work, driving the generator to generate electricity, so that the generated electricity can be transferred to the power distribution equipment in the community, and then the entire community is distributed for use by the residents in the community. And preferably, the geothermal conversion mechanism 11 converts geothermal energy into electrical energy, which can provide self-sufficient power for the shaft parking garage 7, and a charging pile 14 can be installed on the parking plate 3 to charge new energy electric vehicles.

[0028] In this embodiment, in order to reduce costs, the cooler 18 is preferably a cold water tank, etc., in which cooling water is stored. The cooling section is divided into an air inlet section and an air outlet section. The outlet of the air inlet section is connected to the bottom of the cold water tank, so that the heat exchange gas can enter the cold water tank from below and pass through the cooling water in the cold water tank to cool the heat exchange gas. The top of the cold water tank is connected to the air outlet section to discharge the heat exchange gas through the top of the cold water tank and the air outlet section.

[0029] In this embodiment, as a preference, the gas circulation pipeline 20 also includes a heat exchange section located between the cooling section and the working section, and a third heat exchanger 19 is provided between the heat exchange section and the energy storage tank 10 for heat exchange between the two. Specifically, the energy storage mechanism is connected to the external circulation pipeline 21, so that the third heat exchanger 19 is used to respectively connect the external circulation pipeline 21 and the heat exchange section, thereby realizing heat exchange between the external circulation pipeline 21 and the heat exchange section.

[0030] In a specific embodiment, the heat exchange mechanism includes heat exchange rings 2 coaxially arrayed in a vertical direction in a ring structure in a geothermal collection well, each heat exchange ring 2 is sequentially connected along the axial direction of the geothermal collection well, a heat exchange tube 1 is built into the heat exchange ring 2, and a first liquid inlet and a first liquid outlet are opened on the outer wall of the heat exchange ring 2, both of which are connected to the heat exchange tube 1, the first liquid inlet and the first liquid outlet between two adjacent heat exchange rings 2 are connected, and the heat exchange tubes 1 of each heat exchange ring 2 are connected to form a heat exchange circulation loop, and the heat is transferred through the heat exchange ring 2. The geothermal energy is transmitted and stored in the energy storage mechanism; the first circulation pump is used to pressurize the heat exchange circulation loop so that the first heat exchange medium can flow back and forth in the heat exchange circulation loop to transmit the high temperature / low temperature first heat exchange medium, thereby exchanging the cold / heat in the geothermal layer, and then achieving the purpose of exchanging geothermal energy; and by setting the heat exchange ring plate 2, the outer peripheral wall of the heat exchange ring plate 2 can be attached to the inner peripheral wall of the geothermal collection well, thereby achieving a larger heat exchange area between the heat exchange tube 1 and the underground soil, and improving the efficiency of collecting geothermal energy. Preferably, the heat exchange tube 1 is arranged close to the outer peripheral wall of the heat exchange ring plate 2 to achieve effective collection of geothermal energy.

[0031] Furthermore, the shaft parking garage is located on the inner circumference of the space surrounded by each heat exchange ring plate 2. Since the shaft parking garage 7 is arranged in the geothermal collection well, the radial cross-sectional structure of the geothermal collection well is larger. Compared with the traditional small-diameter geothermal collection well, the contact area between the geothermal collection well disclosed in the present invention and the heat exchange ring plate 2 is larger, thereby realizing the effective collection of geothermal energy.

[0032] In a specific embodiment, the heat exchange ring 2 includes a plurality of heat exchange monoliths 15 sequentially spliced ​​along its circumference, the heat exchange monoliths 15 have heat exchange tubes 1 built therein, and the heat exchange monoliths 15 are provided with connection interfaces 16 connected to the heat exchange tubes 1 on both sides along the circumference of the heat exchange ring 2, the two connection interfaces 16 are respectively provided with a second liquid inlet and a second liquid outlet, the second liquid inlet and the second liquid outlet between two adjacent heat exchange monoliths 15 are connected, thereby completing the connection between the heat exchange monoliths 15 constituting the same heat exchange ring 2, so as to ensure that the first heat exchange medium can flow through each heat exchange monolith 15 at one time. It should be noted that the heat exchange tubes 1 in each heat exchange monolith 15 are arranged according to actual conditions, so as to complete the circulation within the same heat exchange ring 2 and the circulation between two adjacent heat exchange rings 2. For example, the heat exchange tube 1 in at least one heat exchange monolith 15 in the same heat exchange ring 2 can be connected with the heat exchange tube 1 in the corresponding heat exchange monolith 15 in the adjacent heat exchange ring 2.

[0033] In this embodiment, as a preference, the heat exchange monolith 15 is prefabricated with concrete and a steel cage, and the heat exchange tube 1 is connected to the steel cage before pouring the concrete. The heat exchange monolith 15 disclosed in the present invention is prefabricated so that it can be made in advance in the factory. Compared with other geothermal structures, its construction and installation are more convenient, which can fully save the time of on-site construction. The heat exchange tube 1 is arranged in the internal space of the heat exchange monolith 15, that is, the heat exchange tube 1 is first connected to the steel cage, and then concrete is poured to form a prefabricated heat exchange monolith 15, which is convenient for the transportation of the heat exchange monolith 15 and the on-site installation work.

[0034] It can be seen that the present invention cooperates with geothermal collection wells, energy storage mechanisms, energy dispatching mechanisms and geothermal conversion mechanisms 11. The geothermal energy extracted from the geothermal collection wells is stored by the energy storage mechanism. The geothermal energy can be dispatched by the energy dispatching mechanism and used directly as a heat source, or it can be converted into electrical energy for use, thereby achieving full utilization of geothermal energy.

Making a geothermal collection well: determine the location of the geothermal collection well, set up a load-bearing mechanism and a hoisting mechanism on the ground, use an excavation mechanism to excavate the ground, and excavate to the required geothermal layer.
