Description

Technical Field

[0001] This utility model belongs to the field of rapid separation of large mass blocks, and specifically relates to a high-pressure cold gas separation impulse system controlled by timing. Background Technology

[0002] For the rapid separation of massive blocks weighing hundreds of tons, the current method used is pyrotechnic separation, such as using solid-propellant retrorockets. However, this method is single-use and not reusable, which inevitably leads to high costs in order to meet the requirement of multiple uses. Furthermore, the exhaust gases from solid-propellant retrorockets can pollute the environment when pyrotechnic separation is used. Moreover, the thrust of solid-propellant retrorockets cannot be adjusted in time when problems are discovered. Therefore, there is an urgent need for a reusable rapid separation impulse system. Utility Model Content

[0003] To address the issue of non-reusability in practical engineering, this invention proposes a time-controlled high-pressure cold gas separation impulse system. Using high-pressure cold gas such as air or nitrogen as a power source, it replaces traditional pyrotechnic power sources. This system is reusable, operates at high speed, and features pressure and temperature monitoring capabilities. It solves the problem of non-reusability in practical engineering, and by setting different pressures, it can achieve different thrust outputs. Therefore, it has the advantage of being environmentally friendly and more suitable for operators.

[0004] The specific technical solution is as follows:

[0005] A high-pressure cold gas separation impulse system controlled by timing, the separation impulse system includes a gas supply and distribution module, a timing control module, and a function execution module. The timing control module is connected to the gas supply and distribution module via a cable, and the gas supply and distribution module is connected to the function execution module via a high-pressure pipeline.

[0006] The gas supply and distribution module includes a high-pressure gas cylinder, a high-pressure gas cylinder manual valve, a safety valve, and a first pressure sensor.

[0007] The high-pressure gas cylinder has an air inlet on its left side for filling the cylinder; a temperature sensor is located on the right side of the high-pressure gas cylinder to directly monitor the temperature change of the gas inside the cylinder.

[0008] The manual valve of the high-pressure gas cylinder is connected to the air inlet and controls the filling of the high-pressure gas cylinder.

[0009] The high-pressure gas cylinder is used to store high-pressure cold gas. The volume and number of the gas cylinders, as well as the type of high-pressure cold gas, can be determined according to the usage requirements.

[0010] The first pressure sensor is used to monitor the pressure of the high-pressure gas cylinder;

[0011] The safety valve is used to automatically release gas when the pressure of the high-pressure gas cylinder in the gas supply and distribution module exceeds a certain limit, so as to protect the safety of the gas supply and distribution module.

[0012] The gas supply and distribution module also includes an intake solenoid valve, an exhaust solenoid valve, an exhaust throttle valve, and a second pressure sensor;

[0013] The intake solenoid valve and exhaust solenoid valve open and close according to the instructions of the timing control module, so as to realize the supply and exhaust of air from the air supply and distribution module to the function execution module.

[0014] The exhaust throttle valve is used to adjust the gas flow rate during exhaust from the gas supply and distribution module and has wide applicability.

[0015] The second pressure sensor is used to monitor the pressure of the functional execution module.

[0016] The timing control module includes a start switch and a PLC controller. The start switch is connected to the PLC controller via a cable. The PLC controller is connected to the intake solenoid valve and the exhaust solenoid valve via cables.

[0017] The timing control module controls the intake solenoid valve and exhaust solenoid valve to operate at specified times via a PLC controller, thereby enabling the air supply and distribution module to provide a power source to the execution module and achieve high-thrust mechanical operation.

[0018] The start switch is used to control the PLC controller to turn on and off, and as a trigger, it has an emergency stop function.

[0019] Furthermore, the function execution module is a cylinder.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0021] (1) This utility model adopts a mechatronics system, which realizes remote mechanical actuation control through electrical means, and provides a certain degree of safety for users and testers.

[0022] (2) This utility model controls the operation of the function execution module according to the timing. For situations with short separation time, it can achieve millisecond-level timing control with high timing control accuracy.

[0023] (3) This utility model can realize the opening and closing functions of the intake solenoid valve and the exhaust solenoid valve at different times through the timing control module. Specifically, it can realize the opening of the intake solenoid valve alone, which is actuated by the cold air actuation device; and the opening of the exhaust solenoid valve alone, which is charged by the air supply and distribution module to the function execution module device. It can also set different time intervals for the intake solenoid valve and the exhaust solenoid valve to open and close.

[0024] (4) This utility model integrates high-pressure gas cylinder, high-pressure pipeline, inlet solenoid valve, exhaust solenoid valve, throttle valve and safety valve into gas supply and distribution system, making the function of gas supply and distribution module more independent. By replacing the function execution module, the gas supply and distribution module can also be used in other occasions.

[0025] (5) This utility model can achieve different impulse outputs by pre-filling the high-pressure gas cylinder with different pressures and different types of gas sources, which can meet different usage occasions and has a wide range of applicability.

[0026] (6) This utility model is equipped with a temperature sensor and a pressure sensor, which can monitor the pressure and temperature of the gas cylinder and the pressure and temperature of the function execution module. In particular, the pressure sensor of the function execution module is placed in the gas supply and distribution module, which makes the structure of the function execution module simpler.

[0027] (7) Safety factors were taken into account in the design of this utility model. Therefore, a safety valve was set in the gas supply and distribution module. The safety valve can be set with a safety pressure according to the usage requirements. When the pressure of the entire module exceeds the safe use, it will automatically release gas.

[0028] (8) This utility model is equipped with a throttle valve, which can adjust the exhaust volume by setting the opening degree of the throttle valve, and has wide applicability. Attached Figure Description
