[0024] Please see Figure 1 , Figure 2 and Figure 3 The high-pressure test tank structure includes:

[0025] Tank 1 is used to house the propeller to be tested and provide a high-pressure water environment;

[0026] A detachable sealing device is provided at the upper and lower ends of the tank body 1 to seal the tank body and allow repeated opening and closing to allow for testing of different types of propellers, including an upper opening assembly and a lower opening assembly;

[0027] The upper opening assembly includes a housing 11, a servo motor 12 is fixedly connected to the top of the housing 11, a turbine 13 is fixedly connected to the output shaft of the servo motor 12, a worm gear 14 is rotatably connected inside the housing 11, and an opening frame 15 is fixedly connected to one end of the worm gear 14.

[0028] The lower opening assembly includes a lower bracket 16, a cylinder 17 is fixedly connected to the lower bracket 16, a sealing shell 18 is fixedly connected to the right side of the cylinder 17, a limit plate is fixedly connected to the lower bracket 16, a limit rod 19 is slidably inserted into the limit plate, and the right side of the limit rod 19 is fixedly connected to the sealing shell 18.

[0029] Through the above technical solution, the tank body 1 is the core component, used to accommodate the propeller to be tested and provide a high-pressure water environment to simulate actual working conditions. The high-pressure test tank consists of the tank body 1 and a detachable sealing device. The sealing device is divided into upper and lower parts. The upper opening component drives the turbine 13 and worm gear 14 mechanism through the servo motor 12, which drives the opening frame 15 to realize the automatic opening and closing of the sealing cover 2. The lower opening component pushes the sealing shell 18 to move horizontally through the cylinder 17. With the help of the limit rod 19 and the limit plate, the sealing shell 18 is accurately aligned with the sealing cover 2, ensuring the stability of the sealing cover 2. The upper and lower double opening design enables quick propeller replacement and improves test efficiency. The turbine 13 and worm gear 14 mechanism has a self-locking function, which can accurately control the opening and closing position of the sealing cover. The cylinder 17 drives the sealing shell 18 in combination with the limit structure to ensure the sealing reliability of the sealing cover 2 under high pressure.

[0030] A sealing cap 2 is provided at the right end of the tank body 1. The sealing cap 2 matches the shape of the opening of the tank body 1. The top of the lower bracket 16 is fixedly connected to the tank body 1. The bottom of the outer shell 11 is fixedly connected to the tank body 1. One end of the opening bracket 15 is fixedly connected to the sealing cap 2.

[0031] Through the above technical solution, a sealing cover 2 is provided at the right end of the tank body 1, the shape of which matches the opening of the tank body 1. The lower bracket 16 and the outer shell 11 are both fixed to the opening frame 15 of the tank body 1 and directly connected to the sealing cover 2. The matching design of the sealing cover 2 and the opening of the tank body 1 ensures that the high-pressure water does not leak. The fixed connection method ensures the overall rigidity of the sealing device and the tank body 1, avoiding deformation under high pressure. The rigid connection between the opening frame 15 and the sealing cover 2 realizes the direct transmission of power and reduces transmission error.

[0032] Tank 1 is made of high-strength, corrosion-resistant materials to withstand the pressure of a high-pressure water environment and prevent corrosion.

[0033] Through the above technical solution, the tank body 1 is made of high-strength material that can withstand the pressure in a high-pressure water environment, preventing the tank body 1 from deforming or cracking.

[0035] Through the above technical solution, the cooling pipe 4 is used to cool the tank 1 to prevent the tank 1 from being damaged due to excessive temperature in a high-pressure water environment. The cooling water inlet and outlet valves 5 are used to control the inflow and outflow of cooling water and regulate the temperature of the tank. Through the cooling system, the temperature of the tank 1 can be effectively controlled to ensure the smooth progress of the test and improve the safety of the tank 1.

[0036] The bottom of the tank 1 is fixedly connected to a support leg 6, and the bottom of the tank 1 is equipped with an inlet and outlet 7.

[0037] Through the above technical solution, the support leg 6 is used to support the tank body 1 and ensure the stability of the tank body 1. The inlet and outlet 7 is used to control the inflow and outflow of water, which facilitates water filling before the test, drainage after the test, and water circulation during the test. The support leg improves the stability of the tank body, and the inlet and outlet 7 facilitates water control and management, thereby improving the convenience and efficiency of the test.

[0038] An automatic exhaust port 8 is installed on the top of tank 1, and a temperature measuring gauge 9 is installed on the top of tank 1.

[0039] Through the above technical solution, the automatic exhaust port 8 is used to automatically exhaust air when water is injected into the tank 1 to prevent air accumulation from affecting the test results. The thermometer 9 is used to measure the temperature inside the tank 1, so that the test personnel can understand the temperature inside the tank at any time. The automatic exhaust port 8 ensures the accuracy of the test, and the thermometer 9 facilitates the test personnel to monitor and manage the temperature inside the tank 1.

[0040] A local pressure gauge 10 is installed on the top of tank 1, and a remote pressure gauge 3 is installed on the top of tank 1.

[0041] Through the above technical solution, the local pressure gauge 10 is used to directly display the pressure value inside the tank 1, which is convenient for the test personnel to observe at any time. The pressure remote transmission gauge 3 is used to transmit the pressure value inside the tank 1 to the control system or monitoring room to realize remote monitoring and management. The local pressure gauge 10 facilitates the test personnel to monitor the pressure inside the tank 1 in real time, and the pressure remote transmission gauge 3 realizes remote monitoring and management, which improves the safety and convenience of the test.
