[0002] Waterproofing the electronic compartment is a basic item for shipboard stabilization. Currently, it is mainly based on traditional dynamic seals or static seals, which are relatively simple in structure and easy to operate. However, the traditional sealing method has the following problems: 1) Dynamic seals currently often use direct contact methods, which have high resistance and are easy to wear. 2) The static sealing method is simple, but the function is limited after sealing, and it cannot rotate or perform other actions, which affects the functional use, and it is very troublesome to replace.

[0016] Electronic compartment fixed to the upper casing.

[0017] As a further improvement of the present invention, the isolation cavity forms a multi-level cavity from the outside to the inside.

[0018] As a further improvement of the present invention, six levels of cavities are formed from the outside of the isolation cavity to the inside.

[0019] As a further improvement of the present invention, the film is a ferromagnetic film.

[0020] As a further improvement of the present invention, the sensor unit includes at least one airflow sensor and at least one humidity sensor, and the airflow sensor and the humidity sensor are respectively located in any two levels of cavities of the isolation cavity.

[0021] As a further improvement of the present invention, the air guide tube is a spiral air guide tube or a rubber tube, and the opening curvature of the air guide tube is downward.

[0022] The second purpose of the present invention is:

[0023] A non-contact dynamic pressure difference waterproof method for a stable electronic warehouse comprises the following steps in sequence:

[0024] Step S1, the air flow sensor and the humidity sensor trigger the power coil when sensing the pressure difference or water entering;

[0025] Step S2: after the power coil is triggered, a magnetic field with the same frequency and inverse direction is generated according to the sensed pressure difference;

[0026] Step S3, the film generates reverse vibration compensation pressure difference at the same frequency as the pressure production under the driving of the magnetic field;

[0027] Step S4: When the pressure difference and water volume are appropriate, the water is discharged and the pressure difference is compensated.

[0028] As a further improvement of the present invention, if the pressure difference or the water volume continues to increase, the following steps are further included in sequence:

[0029] Step S5: After the airflow sensor and the humidity sensor are triggered, the power coil is triggered to continuously operate at high frequency to generate a continuously changing magnetic field;

[0030] Step S6: The film is continuously agitated under the action of the continuously changing magnetic field, and the air pipe pumps air into the air to reverse the pressure difference and drain the moisture in the isolation cavity.

Example

[0042] like Figure 1 As shown,

[0043] One of the purposes of the present invention:

[0044] A non-contact dynamic pressure difference waterproof device for a stable electronic warehouse, comprising an upper shell and a lower shell, and further comprising:

[0048] An air guide tube 4 is wound around the support rod 3 and is used to pump air and generate a reverse pressure difference to push the infiltrated water waves out of the isolation cavity 1. One end of the air guide tube 4 opens downward, and the other end is connected to the opening position of the single-pass rubber pad 6 located in the isolation cavity 1;

[0049] A power coil 5 located below the film 2;

[0050] A load platform 7 located on the upper housing;

[0053] The electronic compartment 11 is fixed on the upper housing.

[0054] Preferably, the isolation cavity 1 forms a multi-level cavity from the outside to the inside.

[0055] Preferably, the isolation cavity 1 forms six levels of cavities from the outside to the inside.

[0056] Preferably, the film 2 is a ferromagnetic film.

[0057] Preferably, the sensor unit includes at least one airflow sensor 8 and at least one humidity sensor 9, and the airflow sensor 8 and the humidity sensor 9 are respectively located in any two levels of cavities of the isolation cavity 1.

[0058] If space permits, the number of isolation cavities 1 may be appropriately increased, and the number of airflow sensors 8 and humidity sensors 9 may be appropriately increased to obtain a smoother pressure difference response.

[0059] Preferably, the air duct 4 can be a spiral air duct or can be connected to a dry space such as a deck cabin on the ship using a common hose.

[0060] The second purpose of the present invention is:

[0061] A non-contact dynamic pressure difference waterproof method for a stable electronic warehouse comprises the following steps in sequence:

[0062] Step S1, the air flow sensor 8 and the humidity sensor 9 trigger the power coil 5 when sensing the pressure difference or water entry;

[0063] Step S2: After the power coil 5 is triggered, it generates a magnetic field of the same frequency and opposite direction according to the sensed pressure difference;

[0064] Step S3: The film 2 generates a reverse vibration compensation pressure difference at the same frequency as the pressure production under the driving of the magnetic field;

[0065] Step S4: When the pressure difference and water volume are appropriate, the water is discharged and the pressure difference is compensated.

[0066] Preferably, if the pressure difference or the water volume continues to increase, the following steps are further included in sequence:

[0067] Step S5: After the airflow sensor 8 and the humidity sensor 9 are triggered, the power coil 5 is then triggered to continuously operate at high frequency to generate a continuously changing magnetic field;

[0068] Step S6 : The film 2 is continuously agitated under the action of the continuously changing magnetic field, and the air pipe 4 pumps air into the air to reverse the pressure difference and drain the moisture in the isolation cavity 1 .

[0069] The present invention relates to a non-contact dynamic pressure difference waterproof device and method for a stabilizing electronic compartment, and specifically to an IPX-6 level waterproof method, which can prevent external rainwater and sea waves from rushing into the stabilizing electronic compartment and causing product failure through electronic control and structural coordination.

[0070] The present invention includes components such as an isolation cavity 1, a ferromagnetic film 2, a support rod 3, a spiral air guide tube 4, a power coil 5, a single-pass rubber pad 6, a load platform 7, an airflow sensor 8, a humidity sensor 9, a bearing ball 10, and an electronic compartment 11. The positions and connection relationships of the components are as follows: the isolation cavity 1 is composed of the gap between the upper shell and the lower shell, and a six-level cavity is formed from the outside to the inside; the bearing ball 10 is used to connect the upper shell and the lower shell; the ferromagnetic film 2 is connected to the support rod 3, and the power coil 5 is below the ferromagnetic film 2; the spiral air guide tube 4 is wound on the support rod 3, one end of which opens downward, and the other end is connected to the opening position of the single-pass rubber pad 6, the airflow sensor 8 and the humidity sensor 9 are respectively at two levels of the isolation cavity, and the electronic compartment 11 is fixed on the upper shell.

[0071] The functions of each component are as follows: the isolation cavity 1 is used to block external rain or surges and prevent them from entering the interior; the airflow sensor 8 and the humidity sensor 9 sense the airflow direction and water ingress; the bearing ball 10 is used to connect the upper and lower shells while keeping them movable; the single-pass rubber pad 6 ensures that under pressure difference conditions, the airflow will only enter from the spiral air duct 4 and be discharged from the isolation cavity 1.

[0072] When there is rain or surge, water will not flow into the electronic cabin 11 because the electronic cabin 11 is isolated from the outside world by the isolation cavity 1; when the external wind and waves increase, water will enter the isolation cavity 1 due to the pressure difference, and the airflow sensor 8 and the humidity sensor 9 in the first-level isolation cavity will preferentially sense the air pressure change and the water ingress, triggering the power coil 5 to switch on and off at a low frequency. When the power coil 5 is switched on and off at a low frequency, it will generate a magnetic field with the same frequency and opposite direction as the external pressure difference to drive the ferromagnetic film 2. The ferromagnetic film 2 offsets the pressure difference by agitating in the same frequency and in the opposite direction, so that the water waves are blocked outside the electronic cabin 11; when the external wind and waves continue to increase and the external water waves continue to impact and surge, the water flows through the first three isolation cavities, triggering the airflow sensor 8 and the humidity sensor 9 to alarm, and this alarm triggers the power coil 5 to work continuously at a high frequency, driving the ferromagnetic film to work continuously, and with the cooperation of the single-pass rubber pad 6, air is continuously pumped in through the spiral air guide tube 4, generating a reverse pressure difference to push the infiltrated water waves out of the isolation cavity. The spiral air guide tube 4 has a large opening and a downward curvature, which ensures that the downward flow of water is greater than the pressure difference flow and does not form a siphon effect under external wind and wave conditions, and air can always be supplied.

[0073] The present invention adopts a non-contact curved surface to isolate the external water environment, and at the same time has a dynamic coil pressure difference compensation mechanism to compensate for the internal and external pressure difference, thereby preventing backflow of water stains caused by temperature changes or wave impacts.

[0074] The invention has a relatively simple structure and different action levels, and adopts graded treatment for different levels of rainwater or surges. It is energy-saving and silent, and the components do not operate continuously, so it is not easy to produce mechanical fatigue.

[0075] The non-contact waterproofing method of the present invention ensures that the overall structure will not generate additional resistance or wear due to waterproofing, thereby ensuring the movement performance of the device.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly referring to the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.
