Specifically, in a more preferred scheme, in order to simulate a deep-sea working environment and complete a pressure-resistant and waterproof capability test of an electrical connector in the deep-sea working environment, the test method of the waterproof socket power-on test equipment for the water environment

The deep sea working environment is simulated through the sealed pressure container, and the pressure of the water column of the multiple meters is set according to the depth of the deep sea. Applying a pressure calculation (equation 1):

megapascals (MPa) =10 kilograms force =100 meters water column

By adopting the two schemes, the pressure in the sealed pressure container is kept stable and is always kept consistent with the set detection pressure.

Scheme 1: the sealed pressure vessel is replenished with pressure from the accumulator as shown in figure 7.

Scheme 2: the sealed pressure vessel is pressurized from the high pressure water pump as shown in figure 2.

The working principle of the energy storage scheme is as follows:

(1) For setting a detection value of the self-operated pressure regulating valve P1 (the pressure regulating valve 707), the pressure of the megapascals is set according to the detected pressure of the water column of meters, and P2 is the pressure of the energy storage device, and P2> P1 is set.

(2) When the pressure of water in the sealed pressure container (shown as P3 according to the display of a pressure gauge) is lower than the set pressure P1 due to leakage, thermal expansion and cold contraction, the self-operated pressure regulating valve (707) is automatically opened, the water in the energy accumulator flows into the sealed pressure container through the water pipe, and when the set value of P1 is reached, the self-operated pressure regulating valve is automatically closed. The check valve (second check valve 706) prevents the backflow of water.

(3) When the pressure of water in the sealed pressure vessel (indicated as P3 by a pressure gauge) becomes higher than a set pressure P1 due to thermal expansion and contraction, the automatic pressure reducing valve (pressure reducing valve 107) is automatically opened, water flows out of the sealed pressure vessel, and when the pressure decreases to P1, the automatic pressure reducing valve is closed, and the pressure of the automatic pressure reducing valve is also set to P1.

4. Scheme 2 high-pressure water pump scheme theory of operation:

(1) The waterproof pressure sensor P4 (pressure sensor 610) is set to detect a pressure value.

(2) Due to the reasons of leakage, thermal expansion and cold contraction of temperature and the like, when the pressure of water in the sealed pressure container is lower than a set pressure P4, the waterproof pressure sensor sends a signal, an electric switch of the high-pressure water pump (the booster water pump 503) is started, the high-pressure water pump starts to work, water in the water tank 501 enters the high-pressure water pump (the booster water pump 503) through the first water inlet pipe 502, and high-pressure water flows into the sealed pressure container through the one-way valve (the first one-way valve 507) and the second water inlet pipe 504; when the pressure of the sealed pressure container reaches a set value, the waterproof pressure sensor sends a signal to cut off the electric switch of the high-pressure water pump, and the high-pressure water pump stops working.

(3) When the pressure of water in the sealed pressure container is higher than the set pressure P4, the automatic pressure reducing valve is opened, water flows out, and when the pressure of the sealed pressure container is reduced to the original set value, the automatic pressure reducing valve is closed.

The test socket electrifying working principle is as follows: when the plug of the power utilization indicator is inserted into the test socket, the test socket is placed in a high-pressure water environment, the test socket is electrified outside, and the indicator lamp is lightened, so that the test socket works normally in a deep sea test environment. In an experimental example, a power-on test was performed in the apparatus using the safety socket disclosed in the applicant's patent CN111682343B, and according to the above steps, the pressure inside the metal housing was set to 1MP and 3MP for power-on observation, and all the test sockets were subjected to a power-on test for 90 days in an underwater power-on test experiment, and were still in a normal power-on state.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the present invention, the term "and/or" describes the association relationship of the associated objects, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one" means one or more than one; "at least one of a and B", similar to "a and/or B", describes an association relationship of associated objects, meaning that three relationships may exist, for example, at least one of a and B may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In the present disclosure, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples" and the like mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

The above description is only for the purpose of creating a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
