[0002] After manufacturing the components for machines that operate on the seabed, the components need to undergo simulated testing to ensure that their parameters meet the standards for use on the seabed. This is because the pressure on the seabed is extremely high, and if the parameters do not meet the standards, the service life and function of the components will be affected. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a water pressure simulation seabed testing device using a combination of a first closed water tank, a second closed water tank, and a test pump. This allows the pressure inside the first closed water tank to be adjusted by the second closed water tank in conjunction with the test pump, making the pressure and temperature inside the first closed water tank comparable to those on the seabed. After manufacturing components for seabed operations, the components are placed in the first closed water tank, and their parameters are observed to determine whether the components meet preset standards. This solves the problem of how to simulate seabed pressure and temperature to test whether manufactured components meet standards.

[0004] To achieve the above objectives, the following technical solution is adopted: A water pressure simulation seabed testing device includes a first closed water tank and a second closed water tank.

The bottom of the first closed water tank is connected to the second closed water tank through a drain pipe, and the first temperature sensor, the first pressure sensor, and the second switch valve are sequentially provided on the drain pipe.

[0005] Preferably, the vent of the vent valve is connected to the first stainless steel water tank, the first stainless steel water tank is provided with a water supply pipe, the water supply pipe is connected to the input end of the first water supply pump, and the output end of the first water supply pump is connected to the interior of the first closed water tank.

[0006] Preferably, the first closed water tank is provided with a drain pipe, the drain pipe is connected to the input end of the first drain pump, and the output end of the first drain pump is connected to the first stainless steel water tank.

[0011] Compared with the prior art, the beneficial effects of this application are: This application employs a method of setting up a first closed water tank and a second closed water tank in conjunction with a test pump to design a water pressure simulation seabed testing device.

Detailed Implementation

[0014] Reference Figure 1 A water pressure simulation seabed testing device includes a first closed water tank 1 and a second closed water tank 2. The first closed water tank 1 is provided with a water inlet pipe 3 and an air outlet pipe 4. The water inlet pipe 3 is connected to the output end of a test pump 5, and the input end of the test pump 5 is connected to the second closed water tank 2. One end of the air outlet pipe 4 is connected to the top of the first closed water tank 1, and the other end is provided with an air vent valve 6. The bottom of the second closed water tank 2 is connected to the top of the first closed water tank 1 through a pipe 7. A first switch valve 8 is provided on the pipe 7. A liquid level sensor 9 is provided on the first closed water tank 1. A second temperature sensor 10, a second pressure sensor 11, and a second vent valve 12 are provided on the second closed water tank 2. The bottom of the first closed water tank 1 is connected to the second closed water tank 2 through a drain pipe 13. A first temperature sensor 14, a first pressure sensor 15, and a second switch valve 16 are sequentially provided on the drain pipe 13.

[0015] In this embodiment, during use, the component to be tested is placed into the first closed water tank 1. Water from the second closed water tank 2 is injected into the first closed water tank 1 via the test pump 5, thereby creating water pressure in the first closed water tank 1. Since air needs to be expelled from the first closed water tank 1 during the water injection process, an air vent pipe 4 is provided to expel air from the first closed water tank 1 during water injection. After the air is expelled, the air vent valve 6 is closed. The liquid level sensor 9 is used to detect the liquid level in the first closed water tank 1. The first temperature sensor 14 and the first pressure sensor 15 are used to detect whether the water pressure and temperature in the first closed water tank 1 have reached the preset values. The pipe 7 is designed to allow the air expelled from the first closed water tank 1 to enter the second closed water tank 2 during the operation of the test pump 5. The second temperature sensor 10 and the second pressure sensor 11 are used to detect the temperature and pressure inside the second closed water tank 2, and the second drain valve 12 is used when it is necessary to drain the water from the second closed water tank 2.

[0016] As a preferred embodiment, the vent of the vent valve 6 is connected to the first stainless steel water tank 17. The first stainless steel water tank 17 is equipped with a water supply pipe 18, which is connected to the input end of the first water supply pump 19. The output end of the first water supply pump 19 is connected to the interior of the first closed water tank 1. This arrangement is intended to allow air to be expelled from the first closed water tank 17 when it is released. If the water level in the second closed water tank 2 is insufficient, water can be pumped from the first stainless steel water tank 17 into the first closed water tank 1 via the first water supply pump 19.

[0017] As a preferred embodiment, the first closed water tank 1 is provided with a drain pipe 20, which is connected to the input end of a first drain pump 21, and the output end of the first drain pump 21 is connected to the first stainless steel water tank 17. By setting up the drain pipe 20 and the first drain pump, the water in the first closed water tank 1 can be drained into the first stainless steel water tank 17 after the test is completed.

[0018] In a preferred embodiment, a main branch pipe 22 and a secondary branch pipe 23 are provided on the pipeline 7 between the first switch valve 8 and the first closed water tank 1. One end of the main branch pipe 22 is connected to the pipeline 7, and the other end is connected to the output end of the second water supply pump 24. The input end of the second water supply pump 24 is connected to the second stainless steel water tank 25. One end of the secondary branch pipe 23 is connected to the main branch pipe 22 between the second water supply pump 24 and the pipeline 7. The other end of the secondary branch pipe 23 is connected to the input end of the second drainage pump 26. The output end of the second drainage pump 26 is connected to the main branch pipe 22 between the second water supply pump 24 and the second stainless steel water tank 25. After setup, the water in the second stainless steel water tank 25 can be replenished to the first closed water tank 1 by the second water pump 24. At the same time, when the water in the first closed water tank 1 needs to be drained after the test, it can also be discharged into the second stainless steel water tank 25. Since the main branch pipe 22 and the secondary branch pipe 23 are used, the drainage and water replenishment do not interfere with each other. However, since the main branch pipe 22 and the secondary branch pipe 23 are connected pipes 7, space is saved.

[0019] As a preferred embodiment, the first stainless steel water tank 17 and the second stainless steel water tank 25 are connected by a connecting pipe 28, and the connecting pipe 28 is equipped with a third switch valve 27. This connection via the connecting pipe 28 allows the first stainless steel water tank 17 and the second stainless steel water tank 25 to be connected.

[0020] As a preferred embodiment, the top of the first closed water tank 1 is connected to a secondary tank 29, the liquid level sensor 9 is mounted on the secondary tank 29, and the end of the vent pipe 4 away from the vent valve 6 is connected to the secondary tank 29. This arrangement ensures that during testing, components are primarily contained within the non-secondary tank 29 of the first closed water tank 1, while venting and other operations are not performed within the non-secondary tank 29 of the first closed water tank 1, thus preventing water from being carried away from the first closed water tank 1 during the venting process.

[0021] As a preferred embodiment, the end of the pipe 7 furthest from the second closed water tank 2 is connected to the auxiliary tank 29. This prevents water from the first closed water tank 1 from being carried into the second closed water tank 2 during the process of venting gas from the first closed water tank 1 into the second closed water tank 2.
