Description

Technical Field

[0001] The utility model belongs to the technical field of water rockets, and particularly relates to a mobile launching platform for water rockets. Background Technique

[0002] A water rocket is a physics teaching aid designed using mass ratio and air pressure. Most water rockets are obtained by modifying the bottle mouth of a beverage bottle, connected to an inflation device through a quick connector, and then launched. By demonstrating the launching action and cultivating the sense of participation during the launching process, students' interest in learning sciences such as physics is stimulated.

[0003] During teaching, it is found that in the process of using existing water rockets, due to the limitations of the water filling and inflation module, students can only participate in activities through processes such as assembly - inflation - launching, and there is less fun in the activities. Therefore, more diverse links need to be developed to promote students' greater sense of participation and improve their interest. However, since the water filling and inflation work of the water rocket needs to be carried out through a pump before launching, there are limitations in the subsequent entertainment scenarios. Summary of the Utility Model

[0033] The water rocket mobile launch platform of the present utility model includes

[0034] A traveling unit 1, which includes an upper clamping plate 11 and a lower clamping plate 12. A storage space 13 is left between the upper clamping plate 11 and the lower clamping plate 12. Track belts are respectively arranged on both sides of the two clamping plates. A plurality of track wheels are wrapped inside the track belts. At the rear of the traveling unit 1, two driving wheels are provided, and the two driving wheels are respectively placed inside the track belts and drive the track belts to move. The two driving wheels are respectively connected to the output shafts of a traveling motor. The rotation of the driving wheels is controlled by the traveling motor. A fixing frame extends outward from the end of the upper clamping plate 11 or the lower clamping plate 12, and the traveling motor is fixedly arranged on the fixing frame. Optionally, in other embodiments, the traveling unit 1 can be arranged in other ways such as wheels;

[0035] A water rocket launch rack 2, which includes a base 21 and a launch panel 22. Support parts 23 extend vertically upward from both sides of the base 21. Connecting parts 24 extend downward from both sides of the launch panel 22. The top ends of the connecting parts 24 and the support parts 23 are rotatably connected. A pitching motor 25 is fixedly arranged on the support part 23. The output shaft of the pitching motor 25 is fixedly connected to the connecting part 24. An operator can control the pitching angle of the launch panel 22 by controlling the rotation angle of the pitching motor 25. In this embodiment, the pitching motor 25 is a reduction motor. A slewing unit 6 is arranged on the upper clamping plate 11, which includes a driving gear 61, a rotating ring 63, and a driven gear ring 62. The rotating ring 63 and the driven gear ring 62 are connected by a bearing. The water rocket launch rack 2 is fixedly arranged on the driven gear ring 62. The driven gear ring 62 meshes with a driving gear 61. In this embodiment, the driving gear 61 is rotatably connected to the upper clamping plate 11. Inside the storage space 13, a slewing motor is arranged. An operator can make the driving gear 61 rotate by controlling the movement of the slewing motor. In this embodiment, a plurality of through holes are formed in the rotating ring 63, and the rotating ring 63 is fixed to the upper clamping plate 11 by screws. Similarly, the driven gear ring 62 is fixedly connected to the base 21 by screws. The driven gear ring 62 can rotate driven by the driving gear 61, thereby driving the water rocket launch rack 2 to perform a slewing motion on the traveling unit 1;

[0036] The launching unit 4 is fixedly installed on the launching panel 22 of the water rocket launching rack 2. There is at least one launching unit 4. In this embodiment, twelve launching units 4 are provided. Each launching unit 4 includes a connector 41 and a control cylinder 42. An active outer ring 43 is provided on the connector 41. When the water rocket is plugged onto the connector 41, the water rocket is fixed by the active outer ring 43. Specifically, the structure of the connector 41 and the cooperation structure between the active outer ring 43 and the water rocket are both prior arts, and their specific structures will not be elaborated here. A connecting member 44 is provided on the active outer ring 43. The cylinder body of the control cylinder 42 is fixed on the launching panel 22, and the piston rod passes through the launching panel 22 and is connected to the active outer ring 43 through the connecting member 44. When the piston rod of the cylinder contracts, it drives the connecting member 44 to press down the active outer ring 43, and the water rocket is unlocked from the connector 41, so that the water rocket is launched. Specifically, a through hole is opened on one side of the connecting member 44, and the connector 41 can pass through the through hole, so that the connecting member 44 presses on the active outer ring 43, and the other side is fixedly connected to the piston rod of the cylinder through a bolt. When the piston rod of the cylinder extends, the active outer ring 43 can be reset by the spring of the connector 41 itself.

[0037] The water storage tank is fixedly installed on the traveling unit 1 through a bracket. In this embodiment, the water storage tank 3 is fixedly installed on the upper clamping plate 11. In other embodiments, the water storage tank 3 can be arranged below the lower clamping plate 12 or in the storage space 13 according to needs. One end of the water storage tank is communicated with a funnel 32, and a throttle valve is provided between the water storage tank 3 and the funnel 32. A water outlet pipe 31 is provided in the water storage tank 3. The inner end of the water outlet pipe 31 is placed at the bottom of the water storage tank 3, and the other end extends out of the water storage tank 3. The water outlet pipe 31 is communicated with the connector 41 through a hose through a multi-stage three-way joint or a multi-way joint, so as to fill water and air into the water rocket on the connector 41;

[0038] An air pump 5 is also fixedly installed on the traveling unit 1. The air outlet of the air pump 5 is communicated with the water storage tank 3. In this embodiment, the air pump 5 is placed in the storage space 13. The air outlet of the air pump 5 is communicated with the water storage tank through a first one-way valve 33. The converging end of the funnel is placed on the pipeline between the first one-way valve and the water storage tank. During use, water can be poured into the water storage tank through the funnel 32. During the water pouring process, the throttle valve is opened so that water flows into the water storage tank 3. At the same time, due to the function of the first one-way valve, water will not enter the air pump; then the air pump 5 is turned on to introduce air into the water storage tank 3. The water in the water storage tank 3 flows out towards the water outlet pipe 31 under the influence of air pressure, so that water enters each water rocket. When all the water in the water storage tank 3 has flowed out, gas is continuously pumped into the water storage tank 3, and gas is filled into the water rocket through the water outlet pipe 31.

[0039] In this embodiment, a second one-way valve 26 is provided between the water outlet pipe 31 and each launching unit 4, thereby preventing the water and gas in the water rocket from flowing back after the water rocket is filled with water and inflated. During use, first, a predetermined amount of water is poured into the water storage tank 3 through the funnel 32, so that the liquid level in the water storage tank 3 submerges the nozzle of the water outlet pipe 31. Then, the air pump 5 is started to introduce gas into the water storage tank 3, so that the water in the water storage tank 3 enters the water rocket through the pipeline. And during this process, there is no need to control the liquid level in each water rocket, so that the liquid levels in each water rocket are different. However, since each water rocket is interconnected through the pipeline, the air pressure in each water rocket is the same. In entertainment, a target can be set, and multiple water rockets can be launched at the same position to observe the hitting situation of the water rockets, so as to facilitate students to observe the influence of different water amounts on the parabola during the launching process of the water rocket under the same air pressure. After that, the launching platform can be moved to different positions by controlling the traveling unit 1 and then launched to hit the target to verify the observed parabola, achieving the effect of combining education with entertainment. A plurality of electromagnetic directional control valves 45 are provided on the launching panel 22, and the electromagnetic directional control valves 45 correspond to the cylinders one by one. The two air outlets of the electromagnetic directional control valve 45 are communicated with the two air ports of the cylinder, and the air inlet of the electromagnetic directional control valve 45 is communicated with the air outlet of the air pump 5. During use, the piston rod of the cylinder 42 can be controlled to contract through the electromagnetic directional control valve, thereby pulling the movable outer ring 43 to move and unlocking the water rocket to complete the launch. Those skilled in the art should know that the air pump 5, the electromagnetic directional control valve 45, and various electrical components such as each motor can be powered by a battery, and the battery can be placed in the storage space 13. In order to facilitate observing the air pressure value in the water rocket, a pressure gauge is connected in series at the outer end of the water outlet pipe 31. The control of the solenoid valve, the electromagnetic directional control valve 45, the air pump 5, and each motor can be carried out in a wired or wireless manner by using a handle. Specifically, in this embodiment, a control module is provided in the storage space 13, and the control signal lines of each electrical component are connected to the control module. The control signals of each component are sent through the buttons or remote sensors of the handle. After receiving the signal, the control module controls the start and stop of each electrical component through electrical signals. The specific control method and the signal transmitting and receiving devices are all prior art in this field and will not be elaborated here.

[0040] In other embodiments, a flow controller can be added between the water outlet pipe 31 and each launching unit 4, and the flow controller is connected in series with the second one-way valve 26, so that the operator can preset the water filling amount of each water rocket.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
