Description

Technical Field

[0001] This utility model relates to the field of jet propulsion device structure, specifically a prototype for simulating the principle of a jet propulsion device. Background Technology

[0002] Jet propulsion systems have a wide range of applications in marine exploration, water transport, and maritime operations. With technological advancements, the performance requirements for jet propulsion systems are constantly increasing. They must not only achieve efficient propulsion but also demonstrate excellent performance in operational stability, precise control, and other aspects to adapt to complex and ever-changing aquatic environments and diverse operational tasks.

[0003] While current jet propulsion systems have achieved some success in fulfilling basic functions, they still fall short in terms of refined control and comprehensive monitoring of the overall system. The coordination between components is not optimized, resulting in poor adaptability to different operating conditions and an inability to fully meet the demands of high-precision operations and scenarios requiring extremely high stability.

[0004] Generally, a motor drives the pump to draw water from the water source into the pump chamber, which then pressurizes the water and delivers it through pipes to the nozzles, generating propulsion. In this process, the control of parameters such as flow rate and pressure relies mainly on relatively simple mechanical adjustment devices or basic sensor monitoring, lacking a systematic, precise control and comprehensive dynamic monitoring system.

[0005] Existing technologies lack the precise flow control achieved by this invention, which involves multi-component coordination throughout the entire process from water intake to spraying. This makes it difficult to accurately monitor and rapidly adjust parameters such as pressure and speed at different stages. For example, flow regulation is not precise enough, leading to fluctuations; pressure monitoring is incomplete, failing to respond promptly to pressure pulsations; and the stability of the water intake process is insufficient, potentially causing backflow and other problems that affect overall propulsion efficiency and stability. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a prototype for simulating the principle of a jet propulsion device, so as to solve the technical problems of unstable flow control and insufficient monitoring in existing jet propulsion devices.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prototype for simulating the principle of a jet propulsion device, comprising a device body, a servo motor inside the device body, an air filter inside the device body in conjunction with the servo motor, the servo motor being connected to a single plunger cylinder via a crank-connecting rod mechanism, a displacement sensor being installed at one end of the single plunger cylinder, a water tank being installed outside the device body, the water intake end of the single plunger cylinder being connected to the water tank output end via a pipe, the water outlet end of the single plunger cylinder being connected to one end of an oil outlet check valve via a pipe, the other end of the oil outlet check valve being connected to one end of a main flow sensor, the other end of the main flow sensor being connected to one end of a main flow regulating valve, the other end of the main flow regulating valve being connected to one end of a first branch flow regulating valve, the other end of the first branch flow regulating valve being connected to one end of a second branch flow regulating valve, the other end of the second branch flow regulating valve being connected to one end of a nozzle, a pressure sensor being connected in parallel on the pipeline between the main flow sensor and the main flow regulating valve, and the other end of the pressure sensor being connected to a pressure gauge.

[0008] By adopting the above technical solution, the servo motor drives the crankshaft to rotate, which in turn drives the single plunger cylinder to reciprocate, thereby achieving the effects of water intake and water ejection.

[0009] The present invention is further configured such that the output end of the water tank is connected to one end of the water suction filter, the other end of the water suction filter is connected to one end of the shut-off valve, the other end of the shut-off valve is connected to one end of the vibration damper, the other end of the vibration damper is connected to one end of the oil suction check valve, and the other end of the oil suction check valve is connected to the water suction end of the single plunger cylinder, thus forming a complete water suction passage.

[0010] By adopting the above technical solution and by setting several devices between the water tank and the suction end of the single plunger cylinder, the stability of water suction in the pipeline is ensured.

[0011] The present invention is further configured such that an accumulator is connected to the pipeline between the oil outlet check valve and the main flow sensor.

[0012] By adopting the above technical solution, the effect of absorbing pipeline pressure pulsation can be achieved.

[0013] The present invention is further configured such that an overflow valve is connected to the water tank, and the overflow valve is connected to the pipeline after the accumulator.

[0014] By adopting the above technical solution, the output pressure of the pipeline is controlled by the overflow valve.

[0015] The present invention is further configured such that a liquid level controller is provided inside the water tank, and a liquid level gauge is provided outside the water tank.

[0016] By adopting the above technical solution

[0017] The present invention is further configured such that a speed sensor is connected to the pipe between the second flow control valve and the nozzle.

[0018] By adopting the above technical solution, the flow rate of the liquid ejected from the nozzle is monitored by setting a speed sensor.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model uses a servo motor to drive a single plunger cylinder via a crank-connecting rod mechanism. When the plunger rod of the single plunger cylinder extends, water from the tank is sequentially drawn into the cylinder through a water suction filter, a stop valve, a vibration damper, and a one-way suction valve. This process successfully converts the motor's rotary motion into the plunger cylinder's linear motion, achieving stable water intake. Simultaneously, with the help of these components, water quality is effectively filtered, liquid flow is flexibly controlled, pipeline vibration is reduced, and liquid backflow is prevented.

[0021] 2. This utility model connects the water outlet end of a single plunger cylinder to an oil outlet check valve, and then, after passing through a series of flow control components such as a main flow sensor and a main flow regulating valve, the liquid is sprayed out through a nozzle. Furthermore, pressure and speed sensors are connected to the relevant pipelines, which can accurately regulate the liquid flow rate, precisely monitor the pressure and speed, ensure the stable operation of the pipeline, absorb pressure pulsations, reasonably control the output pressure, and monitor the water level in the tank in real time.
