Gas storage wells are divided into two types: injection wells and production wells.

[0003] The authorized publication number "CN204476341U" describes "a high-sealing underground gas storage well, including a wellhead structure, a well pipe, a lower end cap, and a drain pipe. The well pipe has a wellhead structure on its upper part, a lower end cap on its lower part, and a drain pipe below the well pipe. The wellhead structure includes a wellhead threaded sleeve, a wellhead end plug, a wellhead connector cap, a first end plug sealing ring, a second end plug sealing ring, and an air inlet / outlet connector. The wellhead threaded sleeve is threadedly connected to the surface casing on the well pipe. The wellhead threaded sleeve and the wellhead end plug are connected by the wellhead connector cap. The upper and lower ends of the mating surface between the wellhead threaded sleeve and the wellhead end plug are respectively provided with a first end plug sealing ring and a second end plug sealing ring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a gas storage well for high-temperature media, comprising:

[0027] Foundation 1;

[0028] Concrete external well 2 is fixedly connected to the foundation 1;

[0029] Gas storage inner well 13 is installed at the center of the concrete outer well 2;

[0030] A buffer mechanism, located inside the concrete outer well 2, is used to buffer the descent of the gas storage inner well 13 during use. The buffer mechanism includes a docking component, an energy-absorbing component, and a buffer spring 3. A base 7 is installed at the bottom of the concrete outer well 2. The bottom of the buffer spring 3 is fixedly connected to the base 7. The docking component is located on the buffer spring 3 and connected to the gas storage inner well 13. The energy-absorbing component is located on the base 7.

[0031] A heat conduction mechanism is installed inside the concrete outer well 2 for temperature transfer within the gas storage inner well 13. The heat conduction mechanism includes a partition component, a heat conduction pipe 9, and a heat conduction grease 14. The heat conduction pipe 9 is installed inside the concrete outer well 2 and is wound around the gas storage inner well 13. The heat conduction grease 14 is filled between the concrete outer well 2 and the gas storage inner well 13.

[0032] In this implementation plan: the concrete outer well 2 separates the foundation 1 from the gas storage inner well 13, preventing the temperature and humidity of the foundation 1 from affecting the storage environment of the gas storage inner well 13. In addition, the outer surface of the concrete outer well 2 is provided with a waterproof layer to improve the waterproof effect. The buffer spring 3 buffers the gas storage inner well 13 to ensure the performance. The thermally conductive silicone grease 14 wraps the heat conduction pipe 9 and adheres to the gas storage inner well 13 to complete the overall heat conduction effect. The heat conduction pipe 9 and the external structure complete the internal heat control.

[0033] Specifically, the docking components include a docking block 5 and a docking groove 6. The docking block 5 is fixedly connected to the top of the damping rod 4 and is connected to the top of the buffer spring 3. The docking groove 6 is opened at the bottom center of the gas storage well 13, and the inner wall of the docking groove 6 is wrapped around the outer surface of the docking block 5.

[0034] In this embodiment, both the docking block 5 and the docking groove 6 are circular, which improves the structural stability during use and ensures the effectiveness of use.

[0035] Specifically, the energy-absorbing component is a damping rod 4, which is fixedly connected to the top center of the base 7, and the top of the damping rod 4 is fixedly connected to the bottom center of the docking block 5.

[0036] In this embodiment, the model of the damping rod 4 can be selected from those available on the market as needed, which will not be elaborated here. The damping rod 4 absorbs the elastic force of the buffer spring 3 to ensure stable use.

[0037] Specifically, the separating component is a sealing ring 8, which is fixedly connected to the inner wall of the concrete outer well 2 near the bottom, and the sealing ring 8 is located directly below the heat-conducting pipe 9.

[0038] In this embodiment: the sealing ring 8 separates the heat pipe 9 from the damping rod 4, preventing the thermal grease 14 from affecting the use of the damping rod 4.

[0039] Specifically, a sealing groove 10 is provided on the top of the foundation 1, and a sealing rubber ring 12 is fixedly connected inside the sealing groove 10.

[0040] In this embodiment, the sealing rubber ring 12 is installed in the sealing groove 10 to ensure the sealing of the gas storage well 13.

[0041] Specifically, a sealing cover 11 is bolted to the top of the foundation 1, and the sealing cover 11 is located directly above the gas storage well 13.

[0042] In this embodiment: the sealing cap 11 is squeezed against the sealing rubber ring 12 to ensure sealing. The sealing cap 11 is provided with a connecting flange, which can be connected to an external device to complete the air conduction.

[0043] When in use, the device is installed in the foundation 1 to achieve overall use. It is connected to the external device through the connecting flange on the sealing cover 11 to complete the gas introduction, so that the stored gas enters the gas storage well 13 for storage. During the storage process, the buffer spring 3 and the damping rod 4 are used for buffering to complete the use. During the storage process, the temperature is controlled by the heat conduction pipe 9 to stabilize the gas in the gas storage well 13.

[0044] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
