Abstract
Description
Technical Field
[0001] This utility model relates to the field of water rocket landing chamber technology, specifically a water rocket parachute chamber. Background Technology
[0002] Water rockets are a technologically advanced and very interesting science and technology project that is frequently used in school science festivals, science summer camps, and study tours.
[0003] Traditionally, water rocket parachute compartments were handmade from Coca-Cola bottles. The process was complex, requiring numerous tools including a scribing tool, utility knife, soldering iron, and hot glue gun. It was difficult to make and suitable only for university students or those with strong hands-on skills, not for elementary school students due to inherent risks. Another option was a 3D-printed, openable parachute compartment. Both of these methods had unstable opening and closing mechanisms. When the parachute opened, the parachute lines easily snagged on the compartment doors. In handmade compartments, the doors and body were glued together with plastic tape. When the doors opened, the parachute lines easily caught on the doors, affecting its opening. Even with two opposing doors, the parachute could easily get caught on the doors due to unpredictable wind direction, hindering its normal operation.
[0004] Furthermore, the success of a water rocket launch hinges primarily on its ability to land safely and return to the ground. A safe landing depends on the timely deployment of the parachute. In practice, we have found that in many cases, due to lack of wind, strong winds, or the parachute lines becoming entangled with the launch vehicle, the parachute fails to deploy. These situations cause the entire vessel to plummet rapidly to the ground, resulting in not only devastating damage to the ship but also posing a significant danger to nearby people and buildings. Although water rockets are relatively light, their high altitude and rapid descent can still cause injury to people and other objects on the ground.
[0005] Therefore, there is an urgent need for a one-piece molding technology that allows the entire parachute cover to detach completely when the parachute compartment is opened. This would effectively avoid the danger of the parachute lines getting caught on the parachute compartment when the water rocket parachute is opened, and greatly improve the water rocket parachute compartment opening efficiency.
[0006] Therefore, we proposed a water rocket parachute compartment to solve the above problems. Utility Model Content
[0007] (a) Technical problem to be solved: In view of the shortcomings of the prior art, this utility model provides a water rocket parachute compartment to solve the problems mentioned in the background art.
[0008] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a water rocket parachute compartment, including a water rocket body, a disc is provided on the top of the water rocket body, a through mounting hole is provided on the disc, the disc is fitted onto the top of the water rocket body through the mounting hole, a through threading hole is provided on the disc, and a ring is fixedly connected to the disc.
[0009] Preferably, solid cylinders A and B are symmetrically fixedly connected to the outer circumference of the disc ring, and a parachute compartment is sleeved on the disc via a ring. A delay knob is fixedly connected to the outer surface of the parachute compartment by screws.
[0010] Preferably, the top of the parachute compartment is symmetrically and fixedly connected with inclined columns, and a blocking column is provided between the two parachute compartments. The blocking column is fixedly connected to the inclined surface of the top of the parachute compartment. A through auxiliary hole is opened on the inclined surface of the top of the parachute compartment. A tethering ring is fixedly connected to the top of the parachute compartment. The auxiliary hole and the blocking column are symmetrically arranged.
[0011] Preferably, an elastic rubber band A is hung on the solid cylinder A, and an elastic rubber band B is fixedly connected in the auxiliary hole.
[0012] Preferably, the water rocket body is fitted with a sleeve ring, and an auxiliary rope is fixedly connected to the sleeve ring.
[0013] Preferably, the inner diameter of the mounting hole is adapted to the outer diameter of the top circle of the water rocket body.
[0014] Preferably, the delay switch has a slot for insertion.
[0015] Preferably, the inclined column is tilted at a 30-degree angle.
[0016] (III) Beneficial Effects: Compared with the prior art, the present invention provides a water rocket parachute compartment, which has the following beneficial effects:
[0017] 1. This utility model, through the design of the blocking column, can bring the following benefits to the overall operation:
[0018] Strengthening the tilting driving force and improving separation efficiency: When the elastic band A is released and a rapid rebound occurs, the rebound force acts on the blocking column to generate an impact force. This impact force directly exacerbates the tilting of the parachute compartment towards the solid cylinder A. The aforementioned actively enhanced tilting trend allows the parachute compartment cover to detach from the main body more quickly and thoroughly, avoiding separation jamming caused by insufficient tilting force, and greatly improving the overall efficiency of the cover's detachment.
[0019] To reduce the risk of parachute line entanglement and ensure smooth parachute deployment: The impact force from the deflector causes the canopy to tilt more significantly, and with the contraction and pulling of the elastic band B, the probability of contact between the parachute canopy and the parachute lines during the detachment of the canopy from the disc is significantly reduced. At the same time, the increased tilt angle allows the parachute to have more space during deployment, reducing the entanglement or scraping between the parachute lines and the canopy from the source, further ensuring that the parachute can deploy quickly after detachment, which meets the core requirement of "avoiding parachute lines getting caught in the canopy".
[0020] Improved stability and reduced environmental interference: In the past, parachute opening was affected by environmental factors such as wind and the weight distribution of the canopy itself, resulting in unstable operation; the blocking column enhances the tilting action through impact force, which is equivalent to providing an "active assistance" for the top cover to detach, reducing the interference of external environment, such as light wind and slight shaking of the canopy, on the separation process, making the opening action of the parachute canopy more controllable and stable, and maintaining high reliability, especially in complex environments.
[0021] 2. Through its overall design, this utility model can bring the following benefits to the overall operation:
[0022] Simplified production process and lowered operation threshold: Unlike existing technologies that require multiple tools such as scribing tools, utility knives, and soldering irons and rely on complex manual steps, the integrated design eliminates the tedious splicing and gluing process and does not require professional tools or high-level manual skills. This makes it easy for groups with weaker hands-on abilities, such as primary school students, to operate, greatly reducing the barrier to use and making it more suitable for promotion in activities for teenagers such as school science festivals and summer camps.
[0023] Reducing safety hazards and improving safety: Compared to the risks of cuts and burns caused by using tools such as utility knives and soldering irons in handmade production, as well as the risk of paracord entanglement caused by 3D-printed double-door design, the integrated design structurally avoids the risks of tool operation; at the same time, the detachable top cover design completely eliminates the problem of paracord snagging on the door, further ensuring the safety of the water rocket recovery process and reducing the threat of rocket body falling to personnel and the environment.

[0032] 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.
[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0034] Example: Please refer to Figures 1 to 6 As shown: A water rocket parachute compartment includes a water rocket body 1, a disc 2 on the top of the water rocket body 1, a through mounting hole 3 on the disc 2, the disc 2 being fitted onto the top of the water rocket body 1 through the mounting hole 3, a through wire hole 4 on the disc 2, a ring 5 fixedly connected to the disc 2, and solid cylinders A6 and B7 symmetrically fixedly connected to the outer circumference of the disc 2 ring, a parachute compartment 8 fitted onto the disc 2 through the ring 5, a delay knob 9 fixedly connected to the outer surface of the parachute compartment 8 by screws, and symmetrically fixed to the top of the parachute compartment 8. There is an inclined column 10, and a blocking column 11 is set between the two parachute compartments 8. The blocking column 11 is fixedly connected to the top inclined surface of the parachute compartment 8. A through auxiliary hole 12 is opened on the top inclined surface of the parachute compartment 8. A tethering ring 1201 is fixedly connected to the top of the parachute compartment 8. The auxiliary hole 12 and the blocking column 11 are symmetrically arranged. An elastic rubber band A13 is hung on the solid cylinder A6. An elastic rubber band B14 is fixedly connected in the auxiliary hole 12. A sleeve ring 15 is fitted on the water rocket body 1. An auxiliary rope 16 is fixedly connected to the sleeve ring 15.
[0035] Among them, the inner diameter of the mounting hole 3 is adapted to the outer diameter of the top circle of the water rocket body 1.
[0036] The threading hole 4 is used to thread the parachute lines. The finally installed parachute will be located in the cavity formed by the fastening of the disc 2 and the parachute compartment 8.
[0037] The ring 5 is used to secure the parachute compartment 8 and prevent it from moving back and forth on the disc 2.
[0038] Solid cylinders A6 and B7 are used to hang elastic bands A13, thereby fixing them to the parachute compartment 8.
[0039] The delay knob 9 is provided with a plug slot, which can be adapted to external plug-in pins and other plug-in limiting devices. For example, when the plug-in pin limits the delay knob 9 through the plug slot, the delay knob 9 will not rotate. When the restriction is released, the elastic band A13 on the delay knob 9 will disengage after a few seconds, and then perform subsequent actions under its elastic force.
[0040] The inclined column 10 is tilted at a 30-degree angle, mainly to support the elastic rubber band A13 wrapped around the parachute compartment 8.
[0041] The function of the blocking post 11 is that when the elastic band A13 hanging on the delay knob 9 is released, the rebound of the elastic band A13 hits the blocking post 11, which can accelerate the opening of the parachute compartment 8 on the disc 2.
[0042] The elastic band B14 can be fixed inside the hole where the auxiliary hole is located, or it can be fixed on the tie ring 1201 used for backup fixing.
[0043] The auxiliary rope 16 is used in conjunction with the elastic band B14.
[0044] Working principle: In use, the perforated ring at the bottom of the parachute compartment 8, i.e., the mounting hole 3 on the disc 2, is fitted onto the top of the water rocket body 1, so that the top of the water rocket body 1 and the top of the disc 2 are on the same plane, marking the installation in place; then the parachute rope is passed through the threading hole 4 and tied to the water rocket body 1, at which point the rocket's parachute and the water rocket body 1 are connected and installed; further, the parachute is folded and placed into the parachute compartment 8, and the parachute is secured in the container composed of the disc 2 and the parachute compartment 8 through the ring 5 on the disc 2.
[0045] Furthermore, the two elastic bands A13 are connected together, with one end of the elastic band A13 hanging on the solid cylinder A6. Then, the elastic band A13 is blocked at the protruding position, i.e., the location of the blocking post 11, by the inclined post 10 on the parachute compartment 8. (See attached diagram.) Figure 2 and appendix Figure 3 Then, it goes back through the solid cylinder B7 below and hangs on the delay switch 9 to adjust the delay time, and is then limited by the external plug-in limiting component.
[0046] Furthermore, the elastic band B14, which is tied to the auxiliary hole 12 of the water rocket body 1, is pulled upwards and its tightness is adjusted. Then, the elastic band B14 is tied together with the auxiliary rope 16 on the loop 15 of the water rocket body 1. When the parachute delay knob 9 is released and opened, the elastic band A13 hanging on the delay knob 9 will quickly rebound at the moment of release. During this rebound, the elastic band A13 will exert an impact force on the blocking post 11. During this process, the elastic band A13, which was originally tied to the auxiliary rope 16, will be pulled upwards. The elastic band B14, which is attached to the parachute compartment 8, also exerts a pulling force on it. Under the combined pulling force, the parachute compartment 8 will open rapidly. Because the elastic band A13 securing the parachute compartment 8 has a relatively large rebound force, and because the parachute compartment 8 opens when the rocket reaches its highest point and begins its descent, the weight of the water rocket body 1 is greater than the weight of the water rocket body 1 device. Therefore, the parachute compartment 8 will move rapidly at this time, pulling out the parachute inside. (See attached diagram.) Figure 4 The above design effectively avoids the parachute or parachute lines getting caught on the parachute compartment 8, greatly increasing the likelihood of the parachute opening.
