Description
Technical Field
[0001] This utility model relates to the field of technology exhibits, specifically a geothermal heat extraction interactive demonstration device. Background Technology
[0002] The Earth's interior is a huge heat source, with temperatures increasing the deeper you go. Geothermal energy extraction utilizes this natural heat source, using technological means to extract underground heat energy for purposes such as heating, power generation, greenhouse cultivation, animal husbandry, and even bathing.
[0003] Current demonstration devices for geothermal heat extraction are mostly limited to showing how heat exchange occurs after the geothermal water is extracted. For example, the document in Chinese Patent Publication No. CN215341661U, titled "A Teaching Demonstration Device for a Detachable Plate Heat Exchanger," primarily focuses on demonstrating the heat exchanger structure. However, there is insufficient demonstration of how geothermal water is extracted from the well and returned, and how the heating water used for heating circulates after heat exchange with the geothermal water. Current popular science demonstrations of geothermal heat extraction and heating water circulation mainly rely on videos or text / images. Clearly, this method lacks interactivity with visitors, fails to stimulate their scientific exploration interest, and is insufficient in inspiring scientific understanding; therefore, it urgently needs to be addressed. Utility Model Content
[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a geothermal heat extraction interactive demonstration device, which builds a physical hardware platform for interactive demonstrations with visitors, effectively stimulating public scientific interest and ultimately achieving excellent scientific enlightenment effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An interactive geothermal heat extraction demonstration device includes an interactive bicycle that can be ridden in place. The fixed base of the interactive bicycle is provided with two pipe interfaces that respectively constitute an extraction well and a reinjection well. It also includes a heat exchange component and a user terminal. The heat exchange component is connected to the extraction well and the reinjection well through an underground water circulation pipe. A heating water circulation pipe is connected between the heat exchange component and the user terminal. Both the underground water circulation pipe and the heating water circulation pipe are provided with a flowing light strip to demonstrate the flow path of water in the circulation pipe. The pedals of the interactive bicycle constitute the opening and closing part for the propulsion of the flowing light strip.
[0006] As a further embodiment of this utility model: the underground water circulation pipe includes a water intake pipe for supplying water from the demonstration well to the heat exchange component and a return pipe for the heat exchange component to return water to the reinjection well, and the light strips installed on the water intake pipe and the return pipe have different colors.
[0007] As a further improvement of this utility model: the light color of the running light strip installed on the water intake pipe is red, and the light color of the running light strip installed on the return pipe is blue.
[0008] As a further improvement of this utility model: the heating water circulation pipe includes a heating pipe for supplying water from the heat exchange component to the user end and a return water pipe for the user end to return water to the heat exchange component, and the light strips installed on the heating pipe and the return water pipe have different colors.
[0009] As a further improvement of this utility model: the light color of the running light strip installed on the heating pipe is red, and the light color of the running light strip installed on the return water pipe is blue.
[0010] As a further embodiment of this utility model: the heat exchange assembly includes a first heat exchange module and a second heat exchange module arranged in parallel. The first heat exchange module includes a first plate heat exchanger, and the second heat exchange module includes a second plate heat exchanger and a heat pump assembly. Both the first and second heat exchange modules are connected to the user end through their respective heating water circulation pipes. The light strips on the heating pipes connecting the first and second heat exchange modules have different color depths.
[0011] As a further improvement of this utility model: the light color of the running light strip on the heating pipe connected to the first heat exchange module is light red, and the light color of the running light strip on the heating pipe connected to the second heat exchange module is dark red.
[0012] As a further improvement of this utility model: the interactive bicycle is equipped with a monitoring module for monitoring the rotation status of the pedal wheel, and the output end of the monitoring module is connected to the controller of the running light strip.
[0013] As a further improvement of this invention, the monitoring module is a Hall effect sensor or an encoder.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application combines science demonstration with cycling, allowing visitors to drive the entire demonstration process through their own physical exertion, transforming passive viewing into active participation and greatly stimulating interest and a desire for exploration. Furthermore, this application uses lighting to demonstrate the extraction, reinjection, and heat exchange with heating water processes of geothermal water. Combined with the visitors' hands-on participation, the entire process of geothermal heat extraction and heating becomes clear, vivid, and engaging, achieving an excellent interactive science popularization effect.
[0015] 2. The light strips on the intake and return pipes of the underground water circulation pipe use red and blue lights respectively, as do the light strips on the heating and return pipes of the heating water circulation pipe. Through the different colored light strips, the flow direction and changes in the hot and cold state of the medium are clearly and dynamically displayed, making the abstract principle concrete and visible.
[0016] 3. The heat exchange components adopt a conventional heat exchange first heat exchange module and an enhanced heat exchange second heat exchange module with heat pump components set in parallel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings: The specific structure of this utility model is as follows: Figure 1-2 As shown, its main structure includes an interactive bicycle 10, an underground water circulation pipe 20, a heating water circulation pipe 30, a user terminal 40, and a heat exchange component.
[0022] Among them, such as Figure 1As shown, the interactive bicycle 10 is an exercise bicycle or a specially designed model fixed to the ground by a fixed base. The fixed base has two pipe interfaces, representing the extraction well 11 for geothermal water extraction and the recharge well 12 for geothermal water return. Figure 2 As shown, a monitoring module 13 is installed near the axle or spokes of the pedal wheel of the interactive bicycle 10, so that the pedal wheel of the interactive bicycle 10 constitutes the opening and closing part of the flowing light strip. In this embodiment, a Hall sensor or encoder is selected to detect the pedaling speed during riding.
[0023] like Figure 1 As shown, the groundwater circulation pipe 20 is used to simulate the circulation path of geothermal water extracted from the extraction well 11 and then flowing back to the reinjection well 12. It consists of an intake pipe 21 and a return pipe 22. One end of the intake pipe 21 is connected to the interface of the extraction well 11, and the other end is connected to the heat exchange component. A red LED light strip is installed on the pipe body. The red light from the LED light strip on the intake pipe 21 propels the geothermal water from the extraction well 11 to the heat exchange component, demonstrating that the geothermal water is high-temperature hot water when it is extracted from the extraction well 11 and transported to the heat exchange component. One end of the return pipe 22 is connected to the heat exchange component, and the other end is connected to the interface of the reinjection well 12. A blue LED light strip is installed on the pipe body. The blue light from the LED light strip on the return pipe 22 propels the geothermal water from the heat exchange component to the reinjection well 12, demonstrating that the geothermal water is low-temperature water when it flows back to the reinjection well 12 after heat exchange in the heat exchange component.
[0024] like Figure 1 As shown, the heating water circulation pipe 30 is used to simulate the circulation path of the heating system between the heat exchange components and the user terminal 40. It consists of a heating pipe 31 and a return pipe 32. The heating pipe 31 connects the heat exchange components and the user terminal 40. A red-lit running light strip is installed on the pipe. The red light from the running light strip propels the heating water from the heat exchange components to the user terminal 40, demonstrating that the heating water is hot water when flowing from the heat exchange components to the user terminal 40. The return pipe 32 connects the user terminal 40 and the heat exchange components. A blue-lit running light strip is installed on the pipe. The blue light from the running light strip propels the heating water from the user terminal 40 to the heat exchange components, demonstrating that the heating water is cold water when it returns to the heat exchange components after being cooled down at the user terminal 40.
[0025] Furthermore, such as Figure 1As shown, in this embodiment, the heat exchange components consist of two parallel sets of first heat exchange modules 50 and second heat exchange modules 60, demonstrating two different heat exchange types. Specifically, the first heat exchange module 50 contains only one first plate heat exchanger 51, demonstrating the conventional heat exchange using a plate heat exchanger. The second heat exchange module 60 contains one second plate heat exchanger 61 and a simulated heat pump assembly 62, demonstrating a two-stage heat exchange process where the plate heat exchanger performs primary heat exchange followed by the heat pump assembly 62. Specifically, the geothermal water side of both the first heat exchange module 50 and the second heat exchange module 60 is connected in parallel to the groundwater circulation pipe 20, while their heating water side is connected to the user end 40 through independent heating water circulation pipes 30. To differentiate them, the light strip on the heating pipe 31 connected to the first heat exchange module 50 uses a light red light, while the light strip on the heating pipe 31 connected to the second heat exchange module 60 uses a dark red light, indicating that the heating water produced by heat exchange through the heat pump assembly 62 has a higher temperature.
[0026] All the sequential light strips are connected to a central controller (not shown in the accompanying drawings), which controls the light propulsion. The controller's input signal comes from the monitoring module 13 on the interactive bicycle 10. The monitoring module 13 detects the riding motion and the pedaling speed during riding, and the controller controls the light propulsion speed of the sequential light strips in a proportional manner based on the pedaling speed.
[0027] It should be noted that the cooperation between the monitoring module 13 and the controller in controlling the flowing light strip is intended to describe the hardware that implements the interactive demonstration function in this application. That is, the controller receives the riding signal from the monitoring module 13 and drives the flowing light strip to perform a dynamic demonstration that is positively correlated with the riding speed, which is a complete signal detection and light and sound interaction logic.
[0028] However, the specific software programs, algorithms, or code used to implement this control logic are all prior art and are not the subject matter of this application. Those skilled in the art will understand that, based on the hardware structure and control requirements disclosed in this application, the same control function can be achieved through various different programming languages and software design methods. Therefore, any specific control software based on the hardware structure of this utility model can be replaced and implemented without departing from the scope of protection of this application.
[0029] Furthermore, it should be noted that this application is a complete demonstration model system. Its core function is to visually simulate and demonstrate the system principles and workflow of geothermal heat extraction and heating through physical means such as lighting and interactive elements. The aforementioned underground water circulation pipe 20, heating water circulation pipe 30, heat exchange components, and user terminal 40 are all simulated physical models. Their interiors are empty or do not have media flow functions. The processes of geothermal water extraction, reinjection, and heat exchange with heating water are indirectly demonstrated through the dynamic changes of the flowing light strip driven by visitors riding bicycles, rather than through the circulation of real fluids. This positioning ensures the safety, low cost, and ease of maintenance of the device, aligning with its fundamental purpose as a science popularization exhibit.
[0030] To facilitate a further understanding of the operating principle of this application, the specific demonstration process of this application is as follows: Visitors board the interactive bicycle 10 and begin riding. The monitoring module 13 detects pedaling motions and speed in real time and sends signals to the controller.
[0031] Based on the received signals, the controller controls the sequential lighting of the light strip according to the preset light propulsion direction (i.e., from the mining well 11 to the heat exchange component, and then to the reinjection well 12; when the light propels to the heat exchange component, the heating water circulation pipe 30 of the heat exchange component to the user end 40 and back to the heat exchange component is circulated synchronously with the circulation path of the groundwater circulation pipe 20 from the heat exchange component back to the reinjection well 12), and the propulsion speed of the light is proportional to the riding speed.
[0032] As visitors ride the bicycle, the red lights of the water intake pipe 21 illuminate the flow of water from the well 11 toward the heat exchange components, symbolizing the extraction of high-temperature geothermal water.
[0033] At the heat exchange component, the heat of the geothermal water is transferred to the heating water. At this time, to simulate the decrease in the temperature of the geothermal water, the color of the light switch on the return pipe 22 changes to blue. The blue light switch on the return pipe 22 is pushed from the heat exchange component to the reinjection well 12 and lit up, symbolizing that the geothermal water flows back to the reinjection well 12 after the heat exchange and cooling.
[0034] Meanwhile, the heating water is heated at the heat exchange component, and the red light of the flowing light strip on the heating pipe 31 is pushed from the heat exchange component to the user end 40 to light up, symbolizing the provision of heating to the user.
[0035] To demonstrate the decrease in return water temperature after heating, the light color of the running light strip on the return water pipe 32 is adjusted to blue. The blue light of the running light strip on the return water pipe 32 moves from the user end 40 towards the heat exchange component, symbolizing that the heating water flows back to the heat exchange component after cooling down, completing the circulation.
[0036] The combination of science demonstration and cycling allows visitors to drive the entire demonstration through their own physical exertion, transforming passive viewing into active participation and greatly stimulating interest and a desire to explore. Furthermore, through this dynamic, colorful light show, combined with visitor participation, the entire process of geothermal heat extraction and supply becomes clear, vivid, and engaging, achieving excellent interactive science education results.
[0037] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0039] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
