Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a ventilation system applied to the sea. Background Art

[0002] In recent years, with the increasingly tense land resources, photovoltaic and wind power generation are eager to explore new installation modes to alleviate the occupation of onshore land by the installed capacity. Therefore, offshore photovoltaic and wind power have emerged as the times require.

[0003] Some electrical modules inside the offshore cabin store insulating gas. In the long-term use, there is a risk of leakage of the insulating gas. The leakage of the insulating gas will cause the oxygen content in the cabin to decrease. When the staff enters the cabin to maintain each electrical module, there is a safety risk. In the past, air inlets and outlets were set on the cabin, and an exhaust fan was configured. When the staff enters the cabin, the exhaust fan can work to replace the gas in the cabin with the outside gas, thereby reducing the maintenance risk. However, due to the heavy salt mist and high humidity in the offshore environment, moisture and salt mist will enter the cabin due to the operation of the exhaust fan, eroding the internal electrical modules and causing unstable power transmission and transformation, and prone to failures and damages. Summary of the Utility Model

A concentration detection module for detecting the concentration of insulating gas inside the cabin is provided inside the cabin. The ventilation system further includes a control box module for controlling the air inlet filtering module and the exhaust module. The control box module is electrically connected to the concentration detection module, the air inlet filtering module, and the exhaust module.

[0006] Further, the air inlet filtering module includes a first base shell, a first ventilation valve, a steam-water separator, and a salt mist filter.

Detailed Embodiments

[0019] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0020] In the embodiments of the present utility model, if there are directional indications (such as up, down, left, right, front, back...), they are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, the directional indications will also change accordingly.

[0021] In addition, in the present utility model, the descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0022] Please refer to Figures 1 to 5 , the ventilation system applied in the present utility model embodiment on the sea includes a cabin body. An air outlet and an air inlet are provided on the cabin body.

[0023] An air intake filtration module is provided at the air inlet of the cabin body, and an air extraction module is provided at the air outlet of the cabin body. The air intake filtration module is used to filter one or more of moisture and salt mist crystals in the air to prevent moisture, salt mist crystals, etc. in the air from entering the cabin body. The air extraction module is used to drive the gas in the cabin body to flow out of the air outlet at an accelerated speed. The air extraction module forms a positive pressure at the air outlet, and it is not easy for external moisture and salt mist crystals to enter the cabin body from the air outlet.

[0024] A concentration detection module for detecting the concentration of insulating gas in the cabin body is provided in the cabin body. The ventilation system further includes a control box module for controlling the air intake filtration module and the air extraction module. The control box module is electrically connected to the concentration detection module, the air intake filtration module, and the air extraction module.

[0025] The control box module integrates devices such as secondary terminals and relays. The concentration detection module transmits the concentration detection signal to the control box module, and the control box module issues action contacts to control the start of the air intake filtration module and the air extraction module.

[0026] The control logic of the control box module for the air extraction module is as follows: when starting, first start the electric control air valve to open, and then start the air extraction fan; when shutting down, first shut down the air extraction fan, and then shut down the electric control air valve. The purpose is to avoid the idling of the fan and reduce the service life loss of the fan.

[0027] As an implementation manner, the air intake filtration module includes a first base shell, a first ventilation valve, a steam-water separator, and a salt mist filter. A first air delivery channel is provided in the first base shell. The rear end of the first air delivery channel communicates with the interior of the cabin body, and the front end of the first air delivery channel communicates with the exterior of the cabin body. A steam-water separator, a salt mist filter, and a first ventilation valve are sequentially arranged in the first air delivery channel from front to back. The first ventilation valve is electrically connected to the control box module.

[0028] In specific implementation, the steam-water separation element can be a physical adsorption moisture adsorption element or a refrigeration water condensation element. The moisture adsorption element can be made of a material that can absorb moisture, such as quicklime, water-absorbing silica gel, etc. The refrigeration water condensation element can be a semiconductor refrigeration sheet. When the water in the air is cooled, it condenses into water droplets, thereby limiting the entry of moisture into the cabin. The salt spray filter can be made of a material that can isolate or adsorb salt spray crystals.

[0029] The steam-water separator is arranged in front of the salt spray filter element, which first filters the water and then filters the salt spray, thereby preventing the water from affecting the performance of the salt spray filter element.

[0030] The first ventilation valve can adopt a first baffle, which is rotatably set on the first base shell. The first baffle is in a normally closed state, so that the first air supply channel is closed. The first baffle can be driven by an electric control push rod and other components. The first baffle is opened by the drive of the electric control push rod, so that the first air supply channel is conductive.

[0031] As an embodiment, the air inlet filter module further includes a first rain shield, which is correspondingly arranged outside the front end of the first air delivery channel. The first rain shield prevents rain or dew from entering the cabin from the air inlet.

[0032] As an embodiment, the exhaust module includes a second base shell and an exhaust fan. A second air supply channel is arranged in the second base shell. The rear end of the second air supply channel is communicated with the interior of the cabin, and the front end of the second air supply channel is communicated with the outside of the cabin. The exhaust fan is arranged at the rear end of the second air supply channel.

[0033] As an embodiment, the exhaust module also includes a second rain shield, and the second rain shield is arranged outside the front end of the second air supply channel.

[0034] As an implementation manner, the exhaust module further includes a second ventilation valve, which is arranged in the second air delivery channel. The second ventilation valve, the exhaust fan and the control box module are electrically connected.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
