Description

Technical Field

[0001] This utility model relates to the field of demonstration exhibits, specifically a demonstration device for an intermittent fountain. Background Technology

[0002] Geyser is a hot spring that erupts intermittently and often occurs in areas with active volcanic activity. Its principle is similar to a giant, natural "pressure cooker": groundwater is continuously heated by geothermal energy in a specific underground cavity structure, undergoing a periodic natural physical process of "heating-boiling-vaporization and pressurization-eruption-recirculation-reheating".

[0003] Most current fountain demonstration devices utilize mechanical negative pressure structures such as air cylinders or negative pressure pumps, as described in the text of Chinese Patent Publication No. CN221651076U entitled "A Fountain Demonstration Device." While these fountain simulation devices can mimic the basic phenomenon of water jet eruption, their driving principle differs fundamentally from that of real geothermal geysers. Real geothermal geysers rely on geothermal energy and specific geological structures, erupting by generating pressure through the periodic release of heated vaporized water, rather than relying on external mechanical forces to create negative pressure. Clearly, existing fountain demonstration devices cannot accurately simulate the core thermodynamic processes and periodic patterns of geothermal geysers. In applications such as popular science education and geological research demonstrations, they suffer from fundamental deviations, making it difficult to intuitively and accurately explain the formation mechanism of natural geysers, thus limiting their educational value. Therefore, a solution is urgently needed. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a demonstration device for geysers, which can more realistically simulate the periodic eruption process of natural geysers based on thermodynamic principles, effectively helping visitors to deeply understand the formation mechanism of geysers and improving the accuracy and intuitiveness of popular science education.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A demonstration device for an intermittent fountain includes a water receiving tank fixed to the upper part of a frame, a water storage container installed at the lower part of the frame, and a heater for heating the water storage container. The water storage container and the lower bottom of the water receiving tank are connected by a drain pipe, and the drain pipe and the penetration point between them are sealed. There is a steam chamber between the liquid surface of the water storage container and the upper wall of the water storage container to accumulate steam and form a high pressure. At room temperature, the lower end of the drain pipe is located below the liquid surface of the water storage container, and the body of the drain pipe is filled with water.

[0006] As a further embodiment of this utility model, it also includes a water baffle that is spaced apart from the upper end of the drain pipe and located on its spray path. The water baffle is fixed to the water receiving tank bracket by a connecting plate, so that a heat dissipation interval for hot water heat dissipation is formed between the outer edge of the water baffle and the water receiving tank.

[0007] As a further improvement of this utility model: the heater is fixed with a double-layer protective cover, which covers the heat source and water storage container of the heater, and has a through hole through which a drainage pipe can pass.

[0008] As a further improvement of this utility model, the protective cover is made of transparent material.

[0009] As a further embodiment of this utility model: the drainage tube includes a water spray pipe, a transfer hose and an insertion pipe arranged sequentially from top to bottom.

[0010] As a further improvement of this utility model: the water receiving tank, the drain pipe and the water storage container are all made of transparent material, and the heater shell also has a transparent window for viewing the water storage container.

[0011] As a further improvement of this utility model, it also includes a U-shaped structural wall from a top view, with the frame arranged inside the structural wall and a display controller fixed to the open side of the structural wall by railings.

[0012] As a further improvement of this utility model: a pressure sensor and a temperature sensor are installed on the water storage container, the output terminals of the pressure sensor and the temperature sensor are electrically connected to the display controller, and the output terminal of the display controller is electrically connected to the heater.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This application simulates the cycle of a real geyser, where a heater heats the water in the storage container, causing some of the water to vaporize (boil) and produce steam. The accumulation of steam increases the internal pressure of the storage container. When the pressure is sufficient to overcome the weight of the water column in the drainage pipe and the system resistance, the high-temperature water and steam propel the water column upwards from the pipe opening, forming a "geyser." The ejected water is collected in a receiving tank and flows back to the storage container through the drainage pipe. As the eruption continues, combined with subsequent natural cooling, the pressure inside the storage container decreases, the water flows back and reheats, entering the next cycle, thus achieving intermittent eruptions. This simulation method realistically simulates the core formation mechanism of natural geysers, overcoming the fundamental bias of existing technologies that rely on mechanical negative pressure, significantly enhancing its educational value.

[0014] 2. Water baffles are spaced apart at the upper end of the drainage pipe and located in its spray path to prevent the sprayed water from splashing everywhere. At the same time, the heat dissipation gap formed by the water baffles and the water receiving tank helps to cool the hot water, simulating the cooling process of hot water spraying out in nature.

[0015] 3. The heater is equipped with a double-layered protective cover, which covers the outside of the heat source and water container of the heater. This effectively prevents visitors from accidentally touching high-temperature components and improves the safety of the device.

[0016] 4. The protective cover is made of transparent material, allowing for easy observation of the heater's operating status and the condition of the bottom area of ​​the water container.

[0017] 5. The transfer hose facilitates the installation and adjustment of the drainage tube position, improving the ease of device assembly.

[0018] 6. The water receiving tank, drainage pipe, and water storage container are all made of transparent material, and the heater shell also has a transparent window that allows a view of the water storage container. The fully transparent or key transparent design allows visitors to clearly observe the entire process of water flow, boiling, eruption, and recirculation inside the device, enhancing the demonstration effect.

[0019] 7. The outermost main body of this application is set as a U-shaped structural wall when viewed from above, forming a semi-enclosed placement space for the rack and its upper structure. The display controller is fixed to the opening side of the structural wall by railings or other structures, further preventing visitors from entering the inner cavity of the structural wall. At the same time, it creates a safe demonstration environment that avoids collisions, effectively avoiding the safety hazard of hot water splashing and scalding caused by the device being knocked over. Meanwhile, the display controller can observe the periodic change curves or values ​​of temperature and pressure, thereby gaining a deeper understanding of the thermodynamic principles and periodic laws of geysers; the display controller can also play live video clips of famous geysers from around the world, deepening visitors' understanding of geysers and enhancing their viewing interest.

[0020] 8. The water storage container is equipped with pressure and temperature sensors. The output terminals of the pressure and temperature sensors are electrically connected to the display controller, and the output terminal of the display controller is electrically connected to the heater. In particular, the display controller can shut off the heater after the fountain erupts based on the received pressure and temperature information in the water storage container to prevent the water storage container from burning dry.

Detailed Implementation

[0025] 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.

[0026] 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 1-3 As shown, its main structure includes a structural wall 70, a frame 10, a water receiving tank 20, a drain pipe 30, a water storage container 40, a heater 50, a protective cover 60, and a display controller 80.

[0027] Since this application involves high-temperature heating of water, creating a safe, collision-free demonstration environment can effectively prevent the safety hazard of hot water splashing and causing burns due to the device being impacted and tipped over. Therefore, if Figure 3 As shown, the outermost main body of this application is a U-shaped structural wall 70 when viewed from above, forming a semi-enclosed placement space for the frame 10 and its upper structure. The display controller 80 is fixed to the opening side of the structural wall 70 by railings or other structures, further preventing visitors from entering the inner cavity of the structural wall 70. Simultaneously, the display controller 80 can observe the periodic change curves or values ​​of temperature and pressure, thereby gaining a deeper understanding of the thermodynamic principles and periodic patterns of geysers. The display controller 80 can also play live-action video clips of famous geysers from around the world, deepening visitors' understanding of geysers and enhancing their viewing interest. Specifically, the display content of the display controller 80 is not limited to the two mentioned above; other content can be customized or fully displayed according to the desired display effect.

[0028] like Figure 1As shown, the frame 10 is fixedly installed in the inner cavity of the structural wall 70. The water receiving tank 20 is fixed on the upper part of the frame 10, and the water storage container 40 is installed on the lower part of the frame 10. Meanwhile, the heater 50 is set at the bottom of the water storage container 40 to heat the water in the water storage container 40.

[0029] Furthermore, such as Figure 1 As shown, the bottom of the water storage container 40 and the water receiving tank 20 are connected by a drain pipe 30. The drain pipe 30 and the bottom of the water receiving tank 20 and the top of the water storage container 40 are sealed with a sealant (such as a sealing ring or sealant) to ensure that the system works under a certain pressure.

[0030] A steam chamber, which accumulates steam to form a high pressure, exists between the liquid surface of the water container 40 and its upper wall. Preferably, the steam chamber exists in the initial state. When the heater 50 operates, the water at the bottom boils and produces steam. This steam chamber is used to accumulate steam and create the pressure necessary to propel the jet. Under pressure, the chamber gradually expands, forcing the water outwards. Of course, if the water level is too high, the reserved steam space is insufficient, or even non-existent, a jetting effect can still be achieved, but the system pressure may be difficult to build up quickly, resulting in weak or delayed jetting. In actual implementation, the size of the steam chamber in the initial state can be adjusted on-site according to the size of the water container 40 and the required jetting height to achieve the desired jetting effect.

[0031] Furthermore, in the initial state at room temperature, the lower end of the drainage pipe 30 is below the liquid surface to ensure effective communication between the drainage pipe 30 and the water in the water storage container 40. During the heating process, the water in the water storage container 40 is heated, and the hot water rises along the drainage pipe 30, forming a fountain.

[0032] The entire body of the drainage pipe 30 is filled with water, forming a continuous water column. The water-filled pipe ensures that the pressure generated by the thermal expansion of the water during heating can effectively act on the entire water column, thereby propelling the water out from the upper end of the drainage pipe 30. Specifically, the drainage pipe 30 can be filled with water first, and then its lower end can be sealed and inserted into the water storage container 40.

[0033] Based on the above, such as Figure 1-3 As shown, a water baffle 21 is fixedly mounted on the water receiving tank 20 via a bracket connected by a connecting plate 22. The water baffle 21 maintains a certain distance from the upper outlet of the drain pipe 30 and is located in its spray path, effectively preventing water from splashing out of the water receiving tank 20 when the water jet is ejected. In addition, the bracket-mounted method of the water baffle 21 leaves a heat dissipation gap between its outer edge and the inner wall of the water receiving tank 20, which helps to cool the sprayed hot water and allows for a quick start to the next demonstration operation.

[0034] Furthermore, such as Figure 1 As shown, the drainage pipe 30 can adopt a segmented structure, for example, including a water spray pipe 31, a transfer hose 32, and an insertion pipe 33 connected sequentially from top to bottom. The transfer hose 32 can be made of heat-resistant silicone tubing, etc. By setting the transfer hose 32, the penetration point between the drainage pipe 30 and the water storage container 40 and the water receiving tank 20 does not need to be coaxial, which facilitates installation and alignment.

[0035] To further enhance the safety of the device demonstration, such as Figure 1 and Figure 2 As shown, a double-layered protective cover 60 is fixedly installed on the outside of the heater 50. The protective cover 60 covers the heat source part of the heater 50 and the lower part of the water storage container 40, providing heat insulation and protection to prevent the user from touching the high-temperature parts. The protective cover 60 has a through hole for the insertion tube 33 of the drainage tube 30 to pass through. Preferably, the protective cover 60 is made of a transparent material (such as heat-resistant glass or transparent plastic) for easy observation.

[0036] Furthermore, to enhance the demonstration effect, the water receiving tank 20, the drainage pipe 30, and the water storage container 40 are preferably made of transparent materials (such as acrylic or glass). A transparent observation window can also be provided on the housing of the heater 50, allowing the user to observe the changes in the state of the water inside the device from all angles.

[0037] Based on the above, such as Figure 1 As shown, a temperature sensor 41 and a pressure sensor 42 are installed on the water storage container 40 to monitor the water temperature and pressure inside the container in real time. Furthermore, the outputs of the temperature sensor 41 and the pressure sensor 42 are electrically connected to the input of a display controller 80, which can display the temperature and pressure values ​​in real time. Simultaneously, the output of the display controller 80 is electrically connected to the heater 50 to control the heating power and on / off state of the heater 50. Specifically, during the heating process of the water storage container 40 by the heater 50, the display controller 80 determines whether the temperature and / or pressure inside the water storage container 40 has reached a threshold value based on the received electrical signals from the temperature sensor 41 and the pressure sensor 42. This allows the controller to shut down the heater 50 after the fountain erupts, preventing the heater 50 from continuously drying out the water storage container 40.

[0038] Working principle: Initially, the water storage container 40 contains water to a certain level, and the drainage pipe 30 is filled with water (in actual implementation, the water receiving tank 20 can also initially store a certain amount of water, so that after some water evaporates, there is no need to frequently replenish the drainage pipe 30). The heater 50 is activated to heat the water at the bottom of the water storage container 40. The water temperature gradually rises, and some water begins to boil and vaporize, producing water vapor. The accumulation of steam causes the internal air pressure of the water storage container 40 to rise continuously. When the air pressure rises high enough to overcome the gravity of the water column in the drainage pipe 30 and the system flow resistance, the high-temperature water and steam mixture in the water storage container 40 will rapidly push the water in the drainage pipe 30 upwards, and spray it out at high speed from the nozzle of the spray pipe 31, forming a fountain water column. Subsequently, the display controller 80 also receives electrical signals from the temperature sensor 41 and the pressure sensor 42 indicating whether the temperature and / or pressure inside the water container 40 has reached a threshold (specifically, this threshold is set based on the current temperature and pressure recorded during multiple manual intermittent fountain eruption tests, so that the fountain has already erupted and formed before the heater 50 is turned off), in order to control the heater 50 to be turned off after the fountain erupts.

[0039] The ejected water is blocked by the water-blocking cover 21 and falls into the water receiving tank 20. During the eruption, a large amount of water and steam is discharged from the water storage container 40, causing a drop in internal pressure and temperature, weakening the eruption force until it stops. Simultaneously, as the temperature of the water and the water storage container 40 decreases to room temperature, a negative pressure gradually forms in the water storage container 40. At this point, under the combined effects of gravity and negative pressure, the water in the water receiving tank 20 flows back to the water storage container 40 through the drainage pipe 30 (which serves as a return channel). The heater 50 can then continue heating, initiating a new round of "heating-pressurization" to prepare for the next eruption. This cycle repeats, forming an intermittent fountain.

[0040] Throughout the process, visitors can observe the changes in water state through transparent components and also observe the periodic changes in temperature and pressure curves or values ​​through the display controller 80, thereby gaining a deeper understanding of the thermodynamic principles and periodic laws of geysers. They can also watch live video clips of famous geysers from around the world, which will enhance their understanding of geysers and increase their interest in watching.
