Description

Technical Field

[0001] This utility model relates to the field of teaching demonstration equipment technology, specifically a water rocket parachute opening device. Background Technology

[0002] Currently, the most common parachute opening device for water rockets is the top-opening type, which means that a parachute is connected to the upper part of the rocket body, and the arrow is gently placed on the outside of the rocket body. The arrow is dropped and the parachute is released by the inertia and gravity of the water rocket as it descends. However, this structure has low safety and reliability and often fails to open in the air.

[0003] Utility model patent CN110379283A discloses a large-capacity split-opening water rocket parachute compartment and the water rocket itself. The compartment has a bullet-shaped body formed by the openable docking of a first shell and a second shell, allowing the compartment to open either side-opening or split-opening. This maximizes the opening area, fully exposing the internal space of the compartment, allowing the contents, including the parachute, to be easily deployed. While this structure overcomes the limitation of traditional top-opening parachutes, it suffers from a complex structure, cumbersome assembly, and requires custom-made shells, resulting in high manufacturing costs. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a water rocket parachute opening device. It adopts a side-opening parachute structure and constructs a parachute compartment based on the original water rocket. This not only ensures that the parachute opens smoothly, but also greatly simplifies the device components, reduces manufacturing costs, and makes it easy to operate, making it more suitable for widespread teaching and demonstration use.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A water rocket parachute deployment device includes a connecting sleeve and an outer cover disposed between two rocket bodies. The two rocket bodies are connected by a mating joint. The connecting sleeve is fitted onto the mating joint. The side of the connecting sleeve is provided with a bracket for installing a parachute deployment control component. The outer cover can surround the rocket body to form a parachute housing area. An elastic pull rope is connected to one side of the outer cover. The outer cover has mounting holes that cooperate with the parachute deployment control component.

[0007] Furthermore, the side of the connecting sleeve is also provided with a mounting bracket for installing the height acquisition device.

[0008] Furthermore, the bracket and the fixing frame can be installed as a whole or separately, or they can be installed on the same side or opposite sides.

[0009] Furthermore, the parachute opening control component can be a servo motor, a spring-loaded timer, a telescopic motor, or a reciprocating motor.

[0010] Compared with the prior art, the advantages and effects of this utility model are:

[0011] 1. It adopts a side-opening structure, which creates a parachute housing area through the outer cover and the rocket body. After the outer cover is opened, it can expose the parachute to the maximum extent, avoid the parachute being obstructed during the opening process, and improve the success rate of parachute opening.

[0012] 2. A connecting sleeve is installed between the rocket bodies to install the parachute opening control component. Through cooperation with the outer casing mounting holes, precise control of parachute opening is achieved. It can also be used to install an altitude measuring and detection device, thus optimizing the assembly structure of the water rocket. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0023] The water rocket parachute deployment device described in this embodiment is as follows: Figure 1As shown in Figure 3, the device includes a connecting sleeve 2 and an outer cover 3 disposed between the two rocket bodies 1. The two rocket bodies 1 are connected by a mating joint 4. The connecting sleeve 2 is fitted onto the mating joint 4. The sides of the connecting sleeve 2 are respectively provided with a bracket 21 for installing the parachute control component 5 and a fixing bracket 22 for installing the altitude acquisition device 6.

[0024] like Figure 4 , 5 As shown, the bracket 21 and the fixing frame 22 can be installed as a whole or separately, or they can be installed on the same side or opposite sides.

[0025] like Figure 6 As shown, the outer cover 3 is rectangular and made of a plastic material with a certain degree of elasticity. One side is connected to an elastic drawstring 31, and the other side has a mounting hole 32 in the middle that mates with the parachute control component 5. The outer cover 3, by curling around the arrow body 1, forms a closed parachute housing area 7 between the two arrow bodies 1, as shown. Figure 7 and 8 As shown.

[0026] like Figure 3 , 7 As shown in Figure 8, the parachute opening control component 5 in this embodiment is a servo motor, and the swing arm of the servo motor can be placed outside the outer cover 3 through the mounting hole 32. The parachute opening control component 5 can also be replaced by a mechanical spring timer, a telescopic motor, or a reciprocating motor, where the spring shaft of the spring timer, the output shaft of the telescopic motor, or the reciprocating motor is equivalent to the swing arm of the servo motor.

[0027] The altitude acquisition device 6 described in this embodiment includes an altitude detection module and a control module. The altitude detection module is electrically connected to the control module, and the control module is electrically connected to the servo motor. The altitude detection module is existing technology, such as the altitude detection module disclosed by the applicant in utility model patent CN205482926U. This module can measure the real-time altitude of the water rocket. When the set parachute opening altitude is reached, the control module can control the servo motor to perform the arm swing action.

[0028] The working principle of this embodiment is as follows:

[0029] 1. Place the connecting sleeve 2 onto the mating connector 4, then connect the upper and lower rocket bodies 1 through the mating connector 4. Install the servo motor (i.e., the parachute opening control unit 5) and the altitude acquisition device 6 onto the connecting sleeve 2, and tie the parachute lines between the two rocket bodies 1.

[0030] 2. Pass the servo arm through the mounting hole 32 of the outer casing 3, roll the outer casing 3 around the side wall of the rocket body 1, then wind the elastic cord 31 around the rolled outer casing 3, and finally hang the elastic cord 31 on the servo arm. The elasticity of the elastic cord 31 will fix the outer casing 3 between the two rocket bodies 1. The area enclosed inside the outer casing 3 is the parachute housing area 7. Figure 7and 8 As shown;

[0031] 3. The altitude acquisition device 6 can collect the real-time altitude of the rocket body 1. When the set parachute opening altitude is reached, the servo motor can be controlled to swing the arm, so that the elastic pull rope 31 is released from the arm. Due to the loss of the restriction of the elastic pull rope 31, the outer cover 3 automatically unfolds and the parachute is released.
