Description

Technical Field

[0001] This invention belongs to the field of main switchboard protection technology, specifically a multi-functional protection device for a ship's main switchboard. Background Technology

[0002] The main switchboard is a combination of switching and control equipment used to distribute power generated by the ship's main power source to all electrical loads used for normal navigation and daily life. It is also known as the main switchboard or main distribution panel. The electrical energy generated by the ship's main generator is supplied to power users through the main switchboard.

[0003] In some existing main distribution boards, the various components are directly exposed inside the cabinet. If there is severe turbulence during the ship's voyage, other components in the cabinet may fall and hit the main distribution board, or the cabinets may tip over and collide due to turbulence. The force may directly act on the components on the main distribution board, causing direct damage to several precision parts, resulting in complicated repairs and high replacement costs. Summary of the Invention

[0006] Back panel, the front surface of which is equipped with a main power distribution board;

[0007] A protective structure for protecting the main power distribution board is installed on the front surface of the back panel. The protective structure includes an arc-shaped protective component located in front of the back panel, a buffer component for cushioning the arc-shaped protective component, a protective airbag installed on the inner surface of the arc-shaped protective component, and an air-filling component for supplying air to the protective airbag. The buffer component cushions the arc-shaped protective component while supplying air to the protective airbag.

[0008] Preferably, the front surface of the backplate is vertically provided with two vertical rails, and the buffer component for cushioning the arc-shaped protective element includes:

[0009] A guide seat is slidably sleeved on the vertical rail, and a rotating plate is rotatably arranged between the guide seat and the upper end of the arc-shaped protective component;

[0010] A piston cylinder located outside the guide seat, with a piston plate horizontally arranged inside the piston cylinder, and a buffer ring fitted on the piston plate to fit the inner wall of the piston cylinder;

[0011] A connecting rod installed between the lower surface of the piston plate and the side of the guide seat.

[0012] Preferably, the buffer component further includes an upper convex plate fixed to the upper end of the vertical rail, the upper convex plate being used to support and fix the upper end of the piston cylinder, and a lower convex plate being provided on the side of the guide seat and fixedly connected to the connecting rod.

[0013] Preferably, the pneumatic inflation component for additional air supply to the vertical rail includes:

[0014] An air pump located behind the main power distribution board is provided with an air outlet pipe and an air filling main pipe.

[0015] Two inflation branch pipes are installed at the lower end of the air outlet pipe, and the lower ends of the two inflation branch pipes are respectively connected to the inner side of the two vertical rails.

[0016] Preferably, a side branch pipe is also provided on the side of the air outlet pipe, and a mounting plate for supporting the air pump is provided between the two vertical rails.

[0017] Preferably, the main power distribution board is provided with an air knife component on its outer side for heat dissipation of components on its surface, the air knife component comprising:

[0019] A side branch pipe is installed on the air outlet pipe, and multiple air supply pipes are connected to the side branch pipe, with each air supply pipe extending into the air knife holder.

[0020] Preferably, the air knife holder is fitted with a continuous adsorption component for drying the area around the main power distribution board, the continuous adsorption component comprising:

[0021] An adsorption frame is attached to the outside of the air knife frame, and an air inlet is provided inside the adsorption frame;

[0022] Multiple fixed posts are respectively installed on the surfaces of the air knife holder and the adsorption frame;

[0023] A waist-shaped plate connecting two adjacent fixed columns.

[0024] Preferably, the outer surface of the air knife holder is uniformly provided with external exhaust holes, which are connected to the air inlet.

[0025] Preferably, the arc-shaped protective component that isolates and protects the parts on the main power distribution board includes:

[0031] (2) The present invention forms an air knife that blows inward around the main power distribution board by combining the air knife component with the air pump. This not only provides rapid heat dissipation for the main power distribution board and a stable working environment for the main power distribution board, but also makes it difficult for impurities and dust to adhere to the surface of the main power distribution board, thus playing a dustproof role and providing stable protection for the main power distribution board.

[0032] (3) The present invention utilizes the sliding connection between the arc-shaped guard plate and the transverse plate, so that the movement of the arc-shaped guard plate will not affect the maintenance and repair of the parts on the surface of the main power distribution board, and the movement of the protective airbag driven by the arc-shaped guard plate will not be affected by multiple air pipes. The arc-shaped guard plate arches outward, increasing the load-bearing strength of external objects, which facilitates better protection of the main power distribution board.

[0045] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figure 1 - Figure 7 This application provides a multi-functional protective device for a ship's main electrical control panel, comprising:

[0048] The back panel 101 has a main power distribution board 102 mounted on its front surface and a mounting bracket 206 provided on its front surface. The main power distribution board 102 is mounted on the mounting bracket 206 and the back panel 101 is mounted on the keel frame inside the cabinet 100.

[0049] A protective structure 200 for protecting the main power distribution board 102 is installed on the front surface of the back panel 101. The protective structure 200 can be installed on both the surface of the main power distribution board 102 and the rear surface of the cabinet 100, providing multi-directional protection for the main power distribution board 102. This increases the stability and safety of the main power distribution board 102. The protective structure 200 creates a safe protection zone in front of the main power distribution board 102, preventing direct impact on the surface components of the main power distribution board 102 even if components fall due to the ship's rocking and swaying. To achieve stable protection, and as the impact increases, multi-level protection measures will be formed in the safety protection area in front of the main power distribution board 102, increasing the safety and stability of the main power distribution board 102. The protection structure 200 includes an arc-shaped protective component 201 located in front of the back plate 101, a buffer component 204 that buffers the arc-shaped protective component 201, a protective airbag 202 installed on the inner surface of the arc-shaped protective component 201, and an air-filling component 205 that supplies air to the protective airbag 202. The buffer component 204 can buffer the arc-shaped protective component 201 while supplying air to the protective airbag 202.

[0050] In this embodiment, preferably, two vertical rails 203 are vertically arranged on the front surface of the back plate 101, and the buffer member 204 for buffering the arc-shaped protective member 201 includes:

[0051] The guide seat 2042 is slidably sleeved on the vertical rail 203. The two are slidably connected and not easily separated. 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 makes it convenient for the arc-shaped protective member 201 to drive the rotating plate 2041 to rotate when it is subjected to force, and drive the guide seat 2042 to move along the vertical rail 203.

[0052] 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 arranged inside the piston cylinder 2045. A buffer ring 2047 that fits the inner wall of the piston cylinder 2045 is sleeved on the piston plate 2046. The buffer ring 2047 can be a rubber ring.

[0053] A connecting rod 2048 is installed between the lower surface of the piston plate 2046 and the side of the guide seat 2042. The connecting rod 2048 can move synchronously with the guide seat 2042.

[0054] In summary, the initial position of the protective airbag 202 is against the inner surface of the arc-shaped protective component 201, and the protective airbag 202 is initially relatively deflated, with no gas filling or only a small amount of gas remaining inside. When an external object attempts to impact the main power distribution board 102, it will first contact the arc-shaped protective component 201. The arc-shaped protective component 201 will deform slightly under the force and move backward, causing the angle between the rotating plate 2041 and the vertical direction to gradually decrease. This will cause the guide seat 2042 to move outward along the vertical rail 203. The movement of the guide seat 2042 will... The connecting rod 2048 moves outward, causing the piston plate 2046 and buffer ring 2047 to move outward. The piston plate 2046 and buffer ring 2047 compress the air inside the piston cylinder 2045. The air inside enters the protective airbag 202 through the side inflation pipe 2049. The friction between the buffer ring 2047 and the inner wall of the piston cylinder 2045 plays a certain role in buffering and distributing the force on the arc-shaped protective component 201. The protective airbag 202 gradually increases in size, expanding the protection range of the main power distribution board 102.

[0055] In this embodiment, preferably, the buffer component 204 further includes an upper convex plate 2044 fixed to the upper end of the vertical rail 203. The upper convex plate 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 to the lower surface of the upper convex plate 2044. The guide seat 2042 is provided with a lower convex plate 2043 fixedly connected to the connecting rod 2048 on its side. The lower convex plate 2043 supports the connecting rod 2048 and facilitates the synchronous movement of the connecting rod 2048 and the guide seat 2042.

[0056] In this embodiment, preferably, the pneumatic inflation component 205 for additionally supplying air to the vertical rail 203 includes:

[0057] 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 equipped with an air outlet pipe 2053, an air valve is installed on the air outlet pipe 2053, and an inflation main pipe 2054 is installed on the air outlet pipe 2053.

[0058] Two inflation branch pipes 2055 are installed at the lower end of the air outlet pipe 2053, which facilitates the gas to enter the two protective airbags 202 respectively along the two inflation branch pipes 2055. The lower ends of the two inflation branch pipes 2055 are respectively connected to the inner side of the two vertical rails 203. Side branch pipes 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 stand 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 stand.

[0059] In summary, when the arc-shaped protective component 201 moves backward under force to the upright, the switch button on the arc-shaped protective component 201 is pressed, and the air pump 2051 operates. At this time, the air valve on the side branch pipe 2056 is closed, while the air valve on the outlet pipe 2053 is open. The air pump 2051 sends gas through the inflation main pipe 2054 into the two inflation branch pipes 2055, and then through the inflation branch pipes 2055 into the protective airbag 202, accelerating the inflation of the protective airbag 202. Part of the inflated gas tries to enter the piston cylinder 2045 through the side inflation pipe 2049, generating a force that squeezes the piston plate 2046 outward from the inside of the piston cylinder 2045. The force is transmitted to the rotating plate 2041 and the arc-shaped protective component 201, increasing the load-bearing strength of the arc-shaped protective component 201 and better buffering and offsetting the force received. This allows the protective airbag 202 to quickly inflate and protect the parts on the surface of the main power distribution board 102, reducing the impact force from the outside. After the impact ends, the arc-shaped protective component 201 can be manually reset, allowing the piston plate 2046 to move inward. The internal space of the piston cylinder 2045 increases, allowing some of the gas in the protective airbag 202 to be drawn out for the next use and for inspection of the main power distribution board 102. The protective airbag 202 has a vent to facilitate the discharge of excess gas.

[0060] Example 2

[0061] Reference Figure 8 - Figure 10 This is the second embodiment of the present invention.

[0062] In this embodiment, preferably, a wind knife component 300 for heat dissipation of its surface components is provided on the outer side of the main power distribution board 102. The wind knife component 300 can cooperate with the air pump 2051 to form a wind knife that blows inward from all sides of the main power distribution board 102, which not only provides rapid heat dissipation for the main power distribution board 102, but also prevents impurities and dust from adhering to the surface of the main power distribution board 102, thus providing a dustproof function. The wind knife component 300 includes:

[0063] The air knife frame 303 located on the outside of the main power distribution board 102 can be U-shaped and has a ventilation channel inside. Multiple internal exhaust holes 304 are evenly opened on the inner surface of the air knife frame 303. The gas entering the ventilation channel can be discharged from the multiple internal exhaust holes 304 and act on the surface of the main power distribution board 102.

[0064] A side branch pipe 2056 is installed on the air outlet pipe 2053. 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. The multiple air supply pipes 301 extend into the air knife frame 303 respectively, so as to facilitate the full introduction of gas into the ventilation duct.

[0065] In this embodiment, preferably, the air knife holder 303 is fitted with a continuous adsorption component 400 for drying the area around the main power distribution board 102. By providing the continuous adsorption component 400, it can cooperate with the air knife component 300 to adsorb moisture around the main power distribution board 102, maintaining the stability and dryness of the working environment of the main power distribution board 102. It can also cooperate with the air knife holder 303 so that gas discharged from the exhaust port on the surface of the air knife holder 303 enters the adsorption frame 401, playing a certain restoring role on the silica gel drying particles filled inside the adsorption frame 401, extending the adsorption and drying time and lifespan of the silica gel drying particles. The continuous adsorption component 400 includes:

[0066] An adsorption frame 401 is attached to the outside of the air knife holder 303. A support frame 302 is provided on the side of the mounting bracket 206. The support frame 302 is fixed to the rear surface of the air knife holder 303. The adsorption frame 401 is filled with silica gel drying particles. The adsorption frame 401 is a mesh frame, which facilitates the adsorption and drying of moisture around the main power distribution board 102. An air inlet 402 is opened inside the adsorption frame 401. External exhaust holes are evenly opened on the outer surface of the air knife holder 303. The external exhaust holes are connected to the air inlet 402, which facilitates the gas to enter the air inlet 402 through the external exhaust holes and then enter the adsorption frame 401, taking away some of the moisture on the surface of the silica gel drying particles and extending the adsorption and drying life of the silica gel drying particles.

[0067] Multiple fixing posts 403 are respectively installed on the surfaces of the air knife holder 303 and the adsorption frame 401;

[0068] When the waist-shaped plate 404, which connects two adjacent fixing posts 403, is attached to the air knife frame 303 of the adsorption frame 401, the fixing posts 403 on the surface of the two are aligned, and the fixing posts 403 pass through the waist-shaped plate 404 and are exposed on the outside. A limiting ring 405 is fitted on the fixing post 403 to limit the waist-shaped plate 404.

[0069] In summary, when the main power distribution board 102 is not subjected to external impact, the air valve on the air outlet pipe 2053 is closed, while the air valve on the side branch pipe 2056 is open. The air pump 2051 operates via another switch button, sending external air into multiple air supply pipes 301 and into the air knife holder 303, and then dissipating it from the evenly distributed internal exhaust holes 304. This forms an air knife effect on the main power distribution board 102, providing air cooling for the components on the surface of the main power distribution board 102, while simultaneously reducing dust particles adhering to the main power distribution board 102. 2. The gas entering the air knife holder 303 enters the adsorption frame 401 through the external exhaust port and air inlet 402 and is discharged outward, taking away some of the moisture on the surface of the silica gel drying particles in the adsorption frame 401, 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 put in or discharged. The discharged gas enters the cabinet 100, which plays a role in air cooling and heat dissipation for other components in the cabinet 100 and provides multiple protections for the main power distribution board 102.

[0070] Example 3

[0071] Reference Figure 11 This is the third embodiment of the present invention.

[0072] In this embodiment, preferably, the arc-shaped protective member 201 that separates and protects the parts on the main power distribution board 102 includes:

[0073] The horizontal plates 2012 are located above and below the main power distribution board 102 respectively. The horizontal plates 2012 are located outside the main power distribution board 102. When they are moved backward to buffer, they will not affect the main power distribution board 102. Rectangular sliding holes are opened on the surface of the horizontal plates 2012.

[0074] Two vertically positioned arc-shaped protective plates 2011 are located in front of the main power distribution board 102. The arc-shaped protective plates 2011 arch outward to increase the load-bearing capacity against external objects and to better protect the main power distribution board 102. The arc-shaped protective plates 2011 are slidably connected to the horizontal plate 2012. Fixed bases 2013 are provided at both ends of the arc-shaped protective plates 2011. A limiting slider 2014 that slides with a rectangular sliding hole is provided on the rear surface of the fixed base 2013. The limiting slider 2014 can be T-shaped to ensure that it slides with the rectangular sliding hole and is not easily disengaged.

[0075] In summary, during use, the arc-shaped guard plate 2011 slides between the two transverse plates 2012, and there is a sufficient safety area between the arc-shaped guard plate 2011 and the main power distribution board 102, preventing direct contact with the parts on the surface of the main power distribution board 102. The deflated protective airbag 202 fits against the inner surface of the arc-shaped guard plate 2011, and the inner surface of the arc-shaped guard plate 2011 is provided with a storage line 207 to limit the storage of the protective airbag 202. The protective airbag 202 is partially fixed to the arc-shaped guard plate 2011. The inner surface is covered by a storage line 207, which is made of easily broken cotton thread. The force of the inflated protective airbag 202 is sufficient to break the cotton thread, while the cotton thread can limit the deflated protective airbag 202, allowing the arc-shaped protective plate 2011 to slide and connect with the horizontal plate 2012. This ensures that the movement of the arc-shaped protective plate 2011 will not affect the maintenance and repair of the parts on the surface of the main power distribution board 102, and the movement of the protective airbag 202 driven by the arc-shaped protective plate 2011 will not be affected by the multiple air tubes.

[0076] Example 4

[0077] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0078] When the main power distribution board 102 is about to be impacted by an external object, it first contacts the arc-shaped protective component 201. The arc-shaped protective component 201, together with the buffer component 204, forms the first barrier to buffer and protect against external objects. As the arc-shaped protective component 201 continues to be subjected to force, it will cooperate with the air-inflating component 205 to make the protective airbag 202 quickly inflate and form the second protective barrier for the main power distribution board 102. At the same time as inflation, it can further increase the load-bearing strength of the arc-shaped protective component 201. The air-inflating component 205, together with the air knife component 300, can play a role in heat dissipation and protection for the main power distribution board 102. The air knife component 300, together with the continuous adsorption component 400, can remove some of the moisture from the dry particles and extend the service life of the dry particles. Each structure can be used independently or combined with each other to form another function, providing multiple protective functions for the main power distribution board 102.

[0079] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
