DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide an energy storage and heating system based on an urban community smart energy parking garage to solve the community parking problem and reduce the city's consumption of traditional energy.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 5As shown, this embodiment provides an energy storage and heating system based on an urban community smart energy parking garage, including a geothermal collection well arranged in the urban community, a vertical shaft parking garage 7 and a heat exchange mechanism, both of which are arranged inside the geothermal collection well, and an energy storage mechanism arranged outside the geothermal collection well; the top of the geothermal collection well extends to the community ground, and a community geothermal energy storage center 4 is provided at the top of the geothermal collection well. By providing the community geothermal energy storage center 4, the supporting equipment of the entire system (such as the energy storage mechanism, etc.) can be placed in the community geothermal energy storage center 4, without the need for additional transportation channels.

[0033] Among them, the vertical shaft parking garage 7 includes a vehicle conveying mechanism 12 that extends vertically and transmits back and forth in the vertical direction. The vehicle conveying mechanism 12 is provided with a plurality of parking boards 3 that are conveyed synchronously therewith. The community geothermal energy storage center 4 is provided with parking spaces 13 for the parking boards 3 to reside, and the community geothermal energy storage center 4 is provided with a vehicle entrance 9 for vehicles to enter the parking boards 3. A vehicle transfer mechanism is provided between the vehicle entrance 9 and the parking spaces 13. Community residents can park their vehicles at the vehicle entrance 9. The vehicles are automatically transferred to the vacant parking boards 3 located at the parking spaces 13 through the vehicle transfer mechanism, ready for parking and retrieval. During the vehicle retrieval process, vehicles in different parking spaces can be exchanged through the vehicle conveying mechanism 12, so that the vehicles can be smoothly unloaded. And because the vertical shaft parking garage 7 is directly located in the community geothermal energy storage center 4, there is no need to build an additional passage to connect the vertical shaft parking garage 7. The entire vertical shaft parking garage 7 based on geothermal collection wells can effectively utilize 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.

[0034] Moreover, the heat exchange mechanism includes a heat exchange circulation loop for collecting geothermal energy and for heat exchange with the energy storage mechanism. 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 cost of use, 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 to a plurality of heat supply circulation pipes 6 in parallel, 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, which stores a second heat exchange medium for energy storage. To reduce operating costs, the second heat exchange medium is preferably water. Multiple heat supply circulation pipes 6 are connected in parallel to the outlet of the energy storage tank 10. Preferably, the structure 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.

[0035] The energy storage and heating system based on the smart energy parking garage in an urban community disclosed in the present invention fully utilizes the community's underground space to build more parking spaces, saving additional underground space land resources and providing more convenience for residents to store and retrieve their cars. By using the first heat exchange medium in the heat exchange circulation loop to exchange geothermal energy, 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 heat-exchanged with the heat exchange circulation loop to complete the storage of geothermal energy. The energy storage mechanism is connected to the heating mechanism to be supplied via a heating circulation pipeline 6 to provide heat energy to the heating mechanism. Geothermal energy is used as the entire energy source for community life, eliminating the need for additional energy transportation and storage costs, reducing the use of traditional energy in urban communities, effectively reducing carbon emissions, and achieving the community's "zero-carbon" living goals.

[0036] 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, making it convenient for residents to store and retrieve vehicles and providing more convenience for residents.

[0037] In one specific embodiment, a community geothermal energy storage center 4 is equipped with an energy dispatching mechanism. This mechanism is equipped with a temperature sensor installed at the heating facility 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. This allows precise control of the thermal energy required by the heating facility. For example, if the heating facility is a community building 5, residents can access geothermal energy according to their needs through the energy dispatching mechanism, precisely controlling the delivery of geothermal energy to their homes, improving the living environment and creating a constant temperature. Furthermore, the energy dispatching mechanism includes a data acquisition and monitoring module, an energy purchasing module, a user interface, and a reporting module. The data acquisition module detects the temperature of the water body storing geothermal energy, thereby providing real-time monitoring of geothermal energy storage and ensuring the fluidity of geothermal energy exchange. Users can purchase stored geothermal energy through the user interface of the community geothermal energy storage center 4. Purchase status and storage quantity are reported to the backend in real time, ensuring the efficient circulation and replenishment of geothermal energy and sufficient energy for the community.

[0038] In one specific embodiment, a community geothermal energy storage center 4 is equipped with a heat pump mechanism, within which a second heat exchange medium circulates. To improve the efficiency of geothermal energy extraction, the preferred second heat exchange medium is Freon or a heat exchange medium such as R22, R417A, or 134A. A first heat exchanger is provided between the heat pump mechanism and the heat exchange loop for heat exchange between the two, and a second heat exchanger is provided between the heat pump mechanism and the energy storage mechanism for heat exchange between the two. The heat exchange loop circulates the first heat exchange medium to exchange geothermal energy resources within the geothermal collection well. The exchanged geothermal energy resources are then extracted by the heat pump mechanism and stored in the energy storage mechanism. It should be noted that, depending on seasonal demand for geothermal energy, such as for heating or cooling, the condenser and evaporator of the heat pump mechanism are switched to exchange heat with the energy storage mechanism via the second heat exchanger, and the evaporator and condenser of the heat pump mechanism are switched to exchange heat with the heat exchange loop via the first heat exchanger.

[0039] In one specific embodiment, the energy storage mechanism is equipped with a geothermal conversion mechanism 11. The geothermal conversion mechanism 11 includes a gas circulation pipeline 20 for heat exchange with the energy storage mechanism. A heat exchange gas, such as water vapor, circulates within the gas circulation pipeline 20. The gas circulation pipeline 20 includes a cooling section and a vertically extending power generation section. A turbine 17, which rotates with the gas flow, is located at the top of the power generation section. The turbine 17 is connected to a generator, which is connected to the community's power distribution equipment. A cooler 18 is located at the cooling section to cool the gas. The geothermal conversion mechanism 11 converts 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 its upward vertical movement. This drives the turbine 17 to rotate, thereby converting the geothermal energy into mechanical energy. The rotation of the turbine 17 generates work, driving the generator to generate electricity. The generated electricity is then transferred to the community's power distribution equipment, distributing it throughout the community for residents' use. Preferably, the geothermal conversion mechanism 11 converts geothermal energy into electrical energy, which can provide self-sufficient power to the shaft parking garage 7. A charging pile 14 can also be installed on the parking plate 3 to charge new energy electric vehicles.

[0040] 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.

[0041] 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 connect the external circulation pipeline 21 and the heat exchange section respectively, thereby realizing heat exchange between the external circulation pipeline 21 and the heat exchange section.

[0042] In a specific embodiment, the heat exchange mechanism includes a heat exchange ring 2 in a ring structure arranged in a coaxial array in a vertical direction in a geothermal collection well. Each heat exchange ring 2 is connected in sequence along the axis 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 provided 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. The heat exchange tubes 1 of each heat exchange ring 2 are connected to form a heat exchange circulation loop. The heat exchanger 1 is connected to the heat exchanger 2 and stored in the energy storage mechanism. The heat exchanger 1 is pressurized by the first circulating pump so that the first heat exchange medium can flow back and forth in the heat exchanger 2 to transfer the high-temperature / low-temperature first heat exchange medium, thereby exchanging the cold / heat in the geothermal layer and achieving the purpose of exchanging geothermal energy. Moreover, by providing the heat exchange ring 2, the outer peripheral wall of the heat exchange ring 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, thereby 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 2 to enable effective collection of geothermal energy.

[0043] Furthermore, the shaft parking garage is located on the inner circumference of the space surrounded by the heat exchange rings 2. The installation of the shaft parking garage 7 within the geothermal collection well increases the radial cross-section of the geothermal collection well. Compared to conventional small-diameter geothermal collection wells, the geothermal collection well disclosed in the present invention has a larger contact area with the heat exchange rings 2, thereby achieving efficient geothermal energy collection.

[0044] In a specific embodiment, the heat exchange ring 2 includes a plurality of heat exchange single pieces 15 spliced in sequence along its circumference, and the heat exchange single piece 15 has a heat exchange tube 1 built in, and the heat exchange single piece 15 is provided with a connecting interface 16 connected to the heat exchange tube 1 on both sides of the circumference of the heat exchange ring 2. The two connecting 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 single pieces 15 are connected, thereby completing the connection between the heat exchange single pieces 15 that constitute the same heat exchange ring 2, so as to ensure that the first heat exchange medium can flow through each heat exchange single piece 15 at one time. It should be noted that the heat exchange tube 1 in each heat exchange single piece 15 is arranged according to actual conditions, which can complete the circulation within the same heat exchange ring 2 and the circulation between two adjacent heat exchange ring pieces 2. For example, the heat exchange tube 1 in at least one heat exchange single piece 15 in the same heat exchange ring 2 can be connected with the heat exchange tube 1 in the corresponding heat exchange single piece 15 in the adjacent heat exchange ring 2.

[0045] In this embodiment, the heat exchanger plate 15 is preferably prefabricated using concrete and a steel cage. The heat exchange tubes 1 are connected to the steel cage before the concrete is poured. The prefabricated heat exchanger plate 15 disclosed herein can be manufactured in advance in a factory, making its construction and installation more convenient than other geothermal structures, significantly reducing on-site construction time. Furthermore, the heat exchange tubes 1 are arranged within the interior space of the heat exchanger plate 15. Specifically, the heat exchange tubes 1 are first connected to the steel cage, and then concrete is poured to form the prefabricated heat exchanger plate 15. This facilitates transportation and on-site installation of the heat exchanger plate 15.

[0046] 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. The present invention is applied to urban communities to extract and store shallow geothermal energy in the city, and to directly utilize geothermal energy and supply it to community residents as heat energy, or to convert geothermal energy into electrical energy for use by community residents. This fully reduces the use of traditional energy in urban communities, effectively reduces carbon emissions, and saves additional underground space and land resources. It should be noted that the first heat exchanger, the second heat exchanger and the third heat exchanger 19 all adopt conventional heat exchanger structures, and their specific structures are not described in detail in this invention.

[0047] Preferably, a method for manufacturing an energy storage and heating system based on an urban community smart energy parking garage comprises the following steps:

[0048] S1. Prefabricate the heat exchanger 15: Prepare concrete, a steel cage, and a mold for making the heat exchanger 15. Install the heat exchange tube 1 in the steel cage and then place it in the mold. Pour concrete into the mold, and dry it after forming. This completes the preparation of the heat exchanger 15.

[0049] S2. Fabrication of geothermal collection well: Determine the location of the geothermal collection well, set up a load-bearing mechanism and a lifting mechanism on the ground, use an excavation mechanism to excavate the ground until the required geothermal layer is reached, and after excavation is completed, pour a concrete base plate at the bottom of the geothermal collection well;

[0050] S3. Installing the heat exchanger sheets 15: Assemble the required number of heat exchanger sheets 15 to form a heat exchanger ring sheet 2. Use the lifting mechanism to lift the heat exchanger ring sheet 2 and sink it into the geothermal collection well, and connect them in sequence along the vertical direction.

[0051] S4, testing: After assembling the heat exchange rings 2, a heat exchange circulation loop is formed, and the flowability of the heat exchange circulation loop is tested;

[0052] S5. Installing the shaft parking garage 7: Installing the shaft parking garage 7 in the geothermal collection well. The shaft parking garage 7 is located in the space surrounded by the heat exchange rings 2;

[0053] S6. Closing the slab: pouring a concrete slab on the top of the geothermal collection well, and building a community geothermal energy storage center 4 on the concrete slab;

[0054] S7. Construction of supporting equipment: An energy storage mechanism, a heat pump mechanism, a geothermal conversion mechanism 11, a vehicle dispatching mechanism 8 and an energy dispatching mechanism are set up in the community geothermal energy storage center 4.

[0055] In summary, the geothermal collection wells of the present invention are preferably located within urban communities, combined with vertical parking garages 7, and a community geothermal energy storage center 4 constructed within the community. This combination of the geothermal collection wells and vertical parking garages 7 fully utilizes the community's underground space, providing residents with a quick and convenient way to store and retrieve their vehicles. Furthermore, the community geothermal energy storage center 4 stores geothermal energy transmitted by heat exchange tubes 1 in heat exchange rings 2 and supplies it to community buildings 5. Geothermal energy can be directly supplied to residential buildings, transforming old urban areas into habitable, temperature-controlled homes. Furthermore, the extracted geothermal energy can be converted into electricity for residents' use and used to charge new energy electric vehicles in the garage, creating a "zero-carbon" green energy community.

[0056] Adaptive changes based on actual needs are all within the scope of protection of the present invention.

[0057] It should be noted that it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
