[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1 See also Figure 1 - Figure 7 , the present application provides a multifunctional protective device for a ship's main switchboard, comprising: The back panel 101 has a main distribution board 102 mounted on its front surface. A mounting bracket 206 is provided on the front surface of the back panel 101. The main distribution board 102 is mounted on the mounting bracket 206. The back panel 101 is mounted on the keel frame inside the cabinet 100. A protective structure 200 is installed on the front surface of the back panel 101 to protect the main distribution board 102. The protective structure 200 can be installed on the surface of the main distribution board 102 or on the rear surface of the cabinet 100, protecting the main distribution board 102 from multiple directions, increasing the stability and safety of the main distribution board 102. By using the protective structure 200, a safe protection area can be formed in front of the main distribution board 102. Even if the device falls due to the turbulence of the ship, it will not directly act on the surface parts of the main distribution board 102, and the main distribution board 102 can be protected. To achieve stable protection, and as the impact becomes greater, multi-level protection measures will be formed in the safety protection area in front of the main distribution board 102, increasing the safety and stability of the main distribution board 102. The protection structure 200 includes an arc-shaped protective member 201 located in front of the back plate 101, a buffering component 204 for buffering the arc-shaped protective member 201, a protective airbag 202 installed on the inner surface of the arc-shaped protective member 201, and an air-filled component 205 for supplying air to the protective airbag 202. The buffering component 204 can buffer the arc-shaped protective member 201 and supply air to the protective airbag 202 at the same time.

[0021] In this embodiment, preferably, two vertical rails 203 are vertically provided on the front surface of the back plate 101, and the buffer member 204 for buffering the arc-shaped protective member 201 includes: A guide seat 2042 is slidably mounted on the vertical rail 203, and the two are slidably connected and are not easily disengaged. A rotating plate 2041 is rotatably arranged between the guide seat 2042 and the upper end of the arc-shaped protective member 201. The initial position of the rotating plate 2041 forms an angle with the vertical direction, which facilitates the rotation of the rotating plate 2041 when the arc-shaped protective member 201 is subjected to force, thereby driving the guide seat 2042 to move along the vertical rail 203. A piston cylinder 2045 is located outside the guide seat 2042. A side inflation tube 2049 is provided between the upper side of the piston cylinder 2045 and the protective airbag 202. A piston plate 2046 is horizontally provided inside the piston cylinder 2045. A buffer ring 2047 is sleeved on the piston plate 2046 and fits against the inner wall of the piston cylinder 2045. The buffer ring 2047 can be a rubber ring. A connecting rod 2048 is installed between the lower surface of the piston plate 2046 and the side surface of the guide seat 2042, and the connecting rod 2048 can move synchronously with the guide seat 2042.

[0022] In summary, the initial position of the protective airbag 202 is in contact with the inner surface of the arc-shaped protective member 201, and the protective airbag 202 is initially deflated, with no gas filled inside or a small amount of gas remaining. When a foreign object wants to hit the main distribution board 102, it will first contact the arc-shaped protective member 201, and the arc-shaped protective member 201 will be slightly deformed and move backward under the force, driving the angle between the rotating plate 2041 and the vertical direction to gradually decrease, driving the guide seat 2042 to move outward along the vertical rail 203, and the movement of the guide seat 2042 will The connecting rod 2048 is driven to move outward, and the piston plate 2046 and the buffer ring 2047 are driven to move outward. The piston plate 2046 and the buffer ring 2047 squeeze the air inside the piston cylinder 2045, and the internal air enters the protective airbag 202 through the side inflation tube 2049. The friction between the buffer ring 2047 and the inner wall of the piston cylinder 2045 plays a certain buffering role in sharing the force on the arc-shaped protective component 201, and the protective airbag 202 gradually becomes larger, expanding the protection range of the main distribution board 102.

[0023] In this embodiment, preferably, the buffer member 204 also includes an upper protrusion 2044 fixed on the upper end of the vertical rail 203, and the upper protrusion 2044 is used to support and fix the upper end of the piston cylinder 2045. The upper end of the piston cylinder 2045 is fixed on the lower surface of the upper protrusion 2044. The side of the guide seat 2042 is provided with a lower protrusion 2043 fixedly connected to the connecting rod 2048. The lower protrusion 2043 supports the connecting rod 2048 and facilitates the synchronous movement of the connecting rod 2048 and the guide seat 2042.

[0024] In this embodiment, preferably, the gas-filled member 205 for additionally supplying air to the vertical rail 203 includes: The air pump 2051 located behind the main power distribution board 102 can supply air to the protective airbag 202. The air pump 2051 is provided with an air outlet pipe 2053, an air valve is provided on the air outlet pipe 2053, and an inflation main pipe 2054 is provided on the air outlet pipe 2053; Two inflation branches 2055 installed at the lower end of the air outlet pipe 2053 facilitate the gas to enter the two protective airbags 202 along the two inflation branches 2055. The lower ends of the two inflation branches 2055 are respectively connected to the inner sides of the two vertical rails 203. Side branches 2056 are also provided on the side of the air outlet pipe 2053. A mounting plate 2052 supporting the air pump 2051 is provided between the two vertical rails 203. A vertical frame is provided on the front surface of the mounting plate 2052, and a switch button for controlling the air pump 2051 is provided on the front surface of the vertical frame.

[0025] In summary, when the arc-shaped protective member 201 is forced to move backward to the stand, the arc-shaped protective member 201 presses the switch button and the air pump 2051 works. At this time, the air valve on the side branch pipe 2056 is closed, and the air valve on the outlet pipe 2053 is opened. The air pump 2051 sends the gas into the two inflation branches 2055 through the inflation main pipe 2054, and then enters the protective airbag 202 through the inflation branch pipe 2055, accelerating the inflation of the protective airbag 202. A part of the injected gas wants to enter the piston cylinder 2045 through the side inflation pipe 2049, generating a force from the inside of the piston cylinder 2045 to squeeze the piston plate 2046 outward. This force It is transmitted to the rotating plate 2041 and the arc-shaped protective member 201, increasing the bearing strength of the arc-shaped protective member 201, better buffering and offsetting the force it receives, so that the protective airbag 202 quickly inflates to protect and buffer the parts on the surface of the main distribution board 102, reducing the external impact force. After the impact is over, the arc-shaped protective member 201 can be manually reset to allow the piston plate 2046 to move inward, and the internal space of the piston cylinder 2045 becomes larger, so that part of the gas in the protective airbag 202 is sucked out for the next use and the main distribution board 102 can be inspected. An air vent is provided on the protective airbag 202 to facilitate the discharge of excess gas in the protective airbag 202.

The air knife component 300 can be used in conjunction with the air pump 2051 to form an air knife that blows inward from all sides of the main distribution board 102, which not only quickly dissipates heat for the main distribution board 102, but also prevents impurities and dust from adhering to the surface of the main distribution board 102, thereby playing a dust-proof role. The air knife component 300 includes: The air knife rack 303 is located outside the main distribution board 102. The air knife rack 303 can be U-shaped and have a ventilation duct inside. The inner surface of the air knife rack 303 is evenly provided with multiple internal exhaust holes 304. The gas entering the ventilation duct can be discharged from the multiple internal exhaust holes 304 and act on the surface of the main distribution board 102. A side branch pipe 2056 is installed on the air outlet pipe 2053, and an air valve is also provided on the side branch pipe 2056. Multiple air supply pipes 301 are connected to the side branch pipe 2056, and the multiple air supply pipes 301 extend to the inside of the wind knife frame 303 respectively, so as to facilitate the full introduction of gas into the ventilation duct.

[0028] In this embodiment, preferably, a continuous adsorption component 400 for drying the periphery of the main distribution board 102 is provided on the wind knife frame 303. By providing the continuous adsorption component 400, it can cooperate with the wind knife component 300 to adsorb moisture around the main distribution board 102 and maintain the stability and dryness of the working environment of the main distribution board 102. It can also cooperate with the wind knife frame 303, so that the gas discharged from the external exhaust port on the surface of the wind knife frame 303 enters the adsorption frame 401, which has a certain recovery effect on the silica gel drying particles filled in the adsorption frame 401, thereby extending the adsorption and drying time and life of the silica gel drying particles. The continuous adsorption component 400 includes: An adsorption frame 401 is fitted on the outside of the wind blade frame 303, a support frame 302 is provided on the side of the mounting frame 206, the support frame 302 is fixed to the rear surface of the wind blade frame 303, the interior of the adsorption frame 401 is filled with silica gel drying particles, the adsorption frame 401 is a mesh frame, which is convenient for adsorbing and drying moisture around the main distribution board 102, an air inlet 402 is provided inside the adsorption frame 401, and external exhaust holes are evenly provided on the outer surface of the wind blade frame 303, and the external exhaust holes are communicated with the air inlet 402, so that the gas can enter the air inlet 402 through the external exhaust holes and then enter the adsorption frame 401, thereby taking away some moisture on the surface of the silica gel drying particles and extending the adsorption and drying life of the silica gel drying particles; A plurality of fixing columns 403 respectively mounted on the surface of the wind blade holder 303 and the adsorption frame 401; The waist-shaped plate 404 connecting two adjacent fixing columns 403 is aligned with the fixing columns 403 on the surfaces of the two surfaces when the adsorption frame 401 is attached to the wind knife holder 303. The fixing columns 403 pass through the waist-shaped plate 404 and are exposed to the outside. A limiting ring 405 is provided on the fixing column 403 to limit the waist-shaped plate 404.

[0029] In summary, when the main distribution board 102 is not subjected to external impact, the air valve on the air outlet pipe 2053 is closed, and the air valve on the side branch pipe 2056 is opened. The air pump 2051 is controlled by another switch button to send the external air into the multiple air supply pipes 301, and pass the air into the air knife frame 303, and discharge it from the evenly distributed inner exhaust holes 304, forming an air knife acting on the main distribution board 102, cooling the parts on the surface of the main distribution board 102, and reducing the adhesion of dust particles to the main distribution board 102. 2, while the other part of the gas entering the wind knife frame 303 enters the adsorption frame 401 through the external exhaust hole and the air inlet 402 and is discharged outward, taking away the moisture on the surface of the silica gel drying particles in the adsorption frame 401, thereby extending the adsorption life and service time of the silica gel drying particles. The surface of the adsorption frame 401 is provided with a door for the silica gel drying particles to be placed in or discharged. The discharged gas enters the cabinet 100, plays a role in air cooling and heat dissipation for other components in the cabinet 100, and plays a multiple protection role for the main distribution board 102.

[0030] Example 3 Reference Figure 11 , which is the third embodiment of the present invention.

[0031] In this embodiment, preferably, the arc-shaped protective member 201 for isolating and protecting the parts on the main distribution board 102 includes: The transverse plates 2012 are located above and below the main distribution board 102. The transverse plates 2012 are located outside the main distribution board 102 and will not affect the main distribution board 102 when moving backward for buffering. The surface of the transverse plates 2012 is provided with rectangular sliding holes. Two arc-shaped guard plates 2011 are vertically located in front of the main distribution board 102. The arc-shaped guard plates 2011 are arched outward to increase the bearing strength against external objects, so as to better protect the main distribution board 102. The arc-shaped guard plates 2011 are slidably connected to the transverse plates 2012. Fixed bases 2013 are provided at both ends of the arc-shaped guard plates 2011. The rear surface of the fixed base 2013 is provided with a limiting slider 2014 that slides with the rectangular sliding hole.

The inner surface, the rest of the part is stored by the storage line 207, and the storage line 207 is a cotton thread that is easy to break, that is, the force of the protective airbag 202 inflating is enough to break the cotton thread, and the cotton thread can limit the deflated protective airbag 202, so that the arc-shaped guard plate 2011 is slidably connected with the transverse plate 2012, so that the movement of the arc-shaped guard plate 2011 will not affect the maintenance and repair of parts on the surface of the main distribution board 102, and the movement of the protective airbag 202 driven by the arc-shaped guard plate 2011 will not be affected by multiple air pipes.

[0033] Example 4 This embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment.

[0034] When the main distribution board 102 is about to be hit by an external object, it first contacts the arc-shaped protective member 201. The arc-shaped protective member 201 cooperates with the buffer component 204 to form a first barrier for buffering and protecting against external objects. As the arc-shaped protective member 201 continues to be subjected to force, it will cooperate with the air-filled component 205 to allow the protective airbag 202 to quickly inflate to form a second protective barrier for the main distribution board 102. While inflating, the bearing strength of the arc-shaped protective member 201 can be further increased. The air-filled component 205 cooperates with the wind knife component 300 to provide heat dissipation protection for the main distribution board 102. The wind knife component 300 is combined with the continuous adsorption component 400 to take away part of the moisture of the dry particles, thereby extending the service life of the dry particles. Each structure can be used independently or combined with each other to form another function, and has multiple protection functions for the main distribution board 102.
