Abstract
Description
Technical Field
[0001] This utility model relates to the field of science education device technology, and more specifically to an electrolytic water rocket launching game device. Background Technology
[0002] Currently, most existing science exhibits demonstrate rocket principles using pneumatic propulsion or video simulations. While pneumatic propulsion devices use mechanical pumps to pressurize air and propel the rocket model, demonstrating the principle of reaction force, they obscure the chemical-to-kinetic energy conversion process of a real rocket. Furthermore, the accumulation and release of air pressure lacks visualization, making it difficult for viewers to perceive the continuity of energy conversion. Multimedia simulation devices rely on video animations to showcase the rocket's workflow, presenting details but depriving viewers of hands-on experience, thus violating the principle of "learning by doing" in science education.
[0003] Therefore, there is a lack of physical interactive devices that allow audiences to directly participate in the energy conversion process. Although there are a few electrolysis rocket devices on the market that attempt physical demonstrations, they also have significant drawbacks: electrolysis rocket devices suffer from low gas collection efficiency, insufficient ignition safety, and complex operation procedures. Utility Model Content

[0014] Furthermore, the operating table protrudes from the steel frame; the handle of the hand-cranked generator is arranged on the operating table.
[0015] Furthermore, the transparent electrolytic cell is in a mountain shape and consists of three vertical tubes and a horizontal connecting pipe;

[0018] Furthermore, a pressure sensor is also installed in the gas collection chamber, and the pressure sensor is connected to the host computer.
[0019] Furthermore, the rocket model is made of PVC material and has a hollow structure; 4 guide fins are arranged at equal intervals circumferentially at the tail.

[0021] Furthermore, the opening pressure of the pressure relief valve is 0.3 MPa.
[0022] Furthermore, a planetary gear speed increasing mechanism is provided between the hand-cranked generator and the handle, with a transmission ratio of 1:15 and an output DC voltage of 12V ± 0.5V.

It is suitable for high-frequency use scenarios such as science museums and schools. Attached Figure Description

[0033] 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.
[0034] This utility model discloses an electrolytic water rocket launching game device, referring to... Figure 1As shown, it consists of a steel frame 1, an operating platform 2, an electrolysis system 3, a gas-driven mechanism 4, a rocket model 5, and a vertical glass pipe 6. The bottom of the steel frame 1 is welded with four anchor bolts with waterproof rubber pads, for example, to secure it to the ground using M12 bolts. The operating platform 2 protrudes from the front of the steel frame, with an ergonomically designed height, such as a 15° tilt. It houses a host computer 21 and has a start button 22 and a launch button 23 on its surface. An LED display screen or LED indicator lights (connected to the host computer) can also be provided to display ignition prompts. In practice, the overall dimensions are 1.3m long × 0.9m wide × 2.8m high. The frame is highly stable, made of cold-rolled steel plate, and features a waterproof design to withstand humid environments; the tilted operating platform enhances user comfort.
[0035] The structure of electrolysis system 3, as follows: Figure 2 The principle shown consists of a hand-cranked generator 31 and a transparent electrolytic cell 32. The handle 33 of the hand-cranked generator 31 extends to the surface of the operating table (e.g., Figure 1 As shown, the internal structure integrates a planetary gear speed-increasing mechanism (transmission ratio 1:15), and the output end is connected to titanium alloy electrode plates 34 (one positive and one negative), with the output DC voltage stabilized at 12V±0.5V. The handle is connected to a permanent magnet generator via a gear set. When the audience shakes the handle, the gear set speeds up the generator, driving it to output DC power to the electrolytic cell. This embodiment does not limit the structure of the gear set or the permanent magnet generator; any structure that achieves the above functions is acceptable.
[0036] The transparent electrolytic cell 32 is made of acrylic and has a mountain-shaped structure, including a first vertical tube 321, a second vertical tube 322, a third vertical tube 323, and a bottom horizontal connecting tube 324. The first vertical tube contains a positive electrode plate (titanium alloy), the third vertical tube contains a negative electrode plate (titanium alloy), and the top of the second vertical tube is equipped with a sealed liquid filling cap.
[0037] The positive and negative electrode plates are connected to the output terminal of the hand-cranked generator 31 via shielded wires; the tops of the first and third vertical pipes are connected to the gas collection chamber 41 of the gas drive mechanism 4 via fluororubber hoses (pressure resistant 0.5MPa). The fluororubber hoses can be covered with a stainless steel braided layer to enhance pressure resistance.
[0038] The principle is as follows: a hand-cranked generator drives electrolysis, with hydrogen and oxygen gases overflowing from the tops of the first and third vertical tubes, respectively. The mountain-shaped structure separates the gas generation areas to prevent mixing and explosion; planetary gears ensure high voltage output at low speeds.
[0039] The structure of the gas-driven mechanism 4 is as follows: Figure 3As shown, it consists of a gas collection chamber 41, a pressure relief valve 42, a piezoelectric igniter 43, and a pressure sensor 44. The gas collection chamber 41 is made of 304 stainless steel, has a volume of 300 mL, a rocket interface on the top, and a pressure relief valve 42 (opening pressure 0.3 MPa) and a piezoelectric igniter 43 installed on the side wall. The pressure sensor 44 is embedded in the inner wall of the collection chamber, with a range of 0-0.5 MPa and an accuracy of ±1%FS.
[0040] The pressure relief valve 42, piezoelectric igniter 43, and pressure sensor 44 are all connected to the host computer 21 via signal lines; the top opening of the collection chamber abuts against the tail end of the rocket model 5.
[0041] The host computer monitors the pressure in real time and automatically opens the pressure relief valve when the pressure exceeds 0.3 MPa; the ignition command is triggered by the launch button. This embodiment employs multiple safety protections to avoid overpressure explosions; the linkage between ignition and pressure enhances reliability.
[0042] Rocket model 5 can be made of PVC material, with a hollow shell (2mm wall thickness), four ABS guide fins welded circumferentially at the tail (90° angle), and a conical fairing on top. As another improvement, a combustion chamber can be installed at the bottom, replacing the aforementioned gas-driven mechanism with a single ignition electrode.
[0043] The vertical glass pipe 6 is made of borosilicate glass (inner diameter Φ80mm), with an inner wall coated with an indium tin oxide transparent conductive layer (surface resistance ≤100Ω / sq). A rubber shock-absorbing ring is installed at the bottom to absorb the impact of the fall, and a magnetic buffer cover (neodymium iron boron magnet attraction force ≥50N) is installed at the top, which can greatly reduce the impact force of the rocket's fall. The pipe is bolted to the steel frame via flanges, and its bottom is coaxially aligned with the rocket interface at the top of the gas collection chamber 41. Additionally, graduations can be installed on the pipe to visually indicate the ascent altitude.
[0044] The rocket model has an outer diameter of Φ78mm and a 1mm gap with the inner wall of the pipe to ensure linear motion. The conductive layer can eliminate electrostatic interference; the magnetic buffer cover and rubber shock absorber ring can achieve flexible braking during rocket descent; and the guide fins improve flight stability.
[0045] In this embodiment, the power generation, electrolysis, and propulsion systems are integrated into a small operating platform to achieve compact electromechanical integration; double protection is provided by rubber shock-absorbing rings and pressure-resistant borosilicate glass tubes to enhance safety; in addition, it has visual teaching elements, using a transparent electrolytic cell and graduated emission tube to intuitively demonstrate the scientific principles.
[0046] The principle demonstrated by the electrolytic water rocket launching game device provided by this utility model is as follows:
[0047] Launch vehicles are tools used to send artificial satellites, spacecraft, space probes, and other space vehicles into predetermined orbits in space. To escape Earth's gravity and deliver payloads into orbit, rockets must possess powerful propulsion systems. The principle behind rocket propulsion is Newton's third law: for every action, there is an equal and opposite reaction. The thrust and number of stages of a rocket depend on the payload capacity and speed requirements. To increase payload capacity, most launch vehicles use booster rockets as the first stage.
[0048] The electrolytic water rocket launching game device provided by this utility model has an overall host computer control principle. Figure 4 As shown, the specific logic is as follows:
[0049] 1) The user presses the start button to activate the hand-cranked generator circuit;
[0050] 2) Then the user operates the hand-cranked generator to start electrolysis;
[0051] 3) When the pressure sensor in the gas collection chamber reaches 0.25 MPa, the ready indicator light will illuminate (or an ignition prompt will be displayed on the LED screen), at which point ignition is permitted;
[0052] 4) When the user presses the launch button, the piezoelectric igniter is triggered to ignite, and the electrolytic circuit is cut off at the same time;
[0053] 5) The downward thrust generated by ignition causes the rocket model to rise along the vertical glass tube to the magnetic cover, and then fall back to the shock-absorbing ring at the bottom.
[0054] The host computer, start button, launch button, pressure sensor, igniter, and pressure relief valve involved are not limited in any way; any existing structure on the market that can achieve the above functions can be used.
[0055] The functions described in this embodiment are all implemented by calling standardized software modules already disclosed in the prior art (such as start command triggering, ignition command triggering, real-time pressure monitoring, etc.). This description is only to illustrate the specific application scenarios of the hardware structure of this application. It should be particularly emphasized that the innovation of this application is only reflected in the structural design, physical connection relationship and modular integration method of the hardware device. The software functions involved (including but not limited to start command triggering, ignition command triggering, real-time pressure monitoring) directly adopt mature existing technical solutions in the market, without making any substantial improvements to the software algorithm, program flow or interaction logic.
