Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an opening and closing switch of a marine pneumatic shutter. Background Art

[0002] Marine chimney shutters play a variety of roles on ships. First, they can adjust the ventilation of the chimney and help control the temperature and humidity inside the ship. By adjusting the opening and closing angles of the shutters, the ventilation of the chimney can be adjusted, thereby providing good air flow, exhausting the heat and harmful gases inside the ship, and maintaining a comfortable environment in the cabin.

[0003] Secondly, marine chimney shutters can also prevent water from entering the chimney. During navigation, especially in severe sea conditions, seawater may rush into the chimney, damaging the internal equipment of the ship and endangering safety. The shutters can effectively prevent seawater from entering the chimney and reduce this risk.

[0004] At the same time, marine chimney shutters can also block wind and rain from entering the cabin, keeping the interior of the ship dry, which is very important for maintaining ship equipment and protecting the safety of cargo and crew.

[0005] The traditional pneumatic shutters have limited functions due to the unidirectional reciprocating action of the cylinder. They are either "ventilation closed, manually opened" or "ventilation opened, manually closed". There are two working states. If special circumstances occur, such as a fire in the engine room, or equipment and pipelines are damaged, the compressed air supply pipeline cannot work normally. In this case, the shutters cannot be closed normally, making it difficult to isolate air from entering and control the fire, posing a great safety hazard to the safety of the ship.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an opening and closing switch for a marine pneumatic shutter comprises: a manual switch and a pneumatic switch arranged on the shutter for controlling the opening and closing of the shutter; and also comprises: a first box body 3, which is arranged on the ship, a sealing tank 31 is fixedly installed inside the first box body 3 by screws, an air inlet pipe 32 is fixedly connected to one side of the outer periphery of the first box body 3 by screws, one end of the air inlet pipe 32 penetrates into the first box body 3 and is fixedly plugged into the sealing tank 31, an air inlet valve 33 is fixedly installed on the air inlet pipe 32 on the outer periphery of the first box body 3 by screws, an air outlet pipe 34 is fixedly connected to the other side of the outer periphery of the first box body 3 by screws, one end of the air outlet pipe 34 penetrates into the first box body 3 and is fixedly plugged into the sealing tank 31, an air outlet valve 35 is fixedly installed on the air outlet pipe 34 on the outer periphery of the first box body 3 by screws, and the air outlet end of the air outlet pipe 34 is connected to the pneumatic switch.

[0025] Among them, by linking the manual switch and the pneumatic switch to control the shutters, the crew can select the desired switching mode according to the state of the ship. When the ship is in a stopped state, manual intervention can be performed to achieve flexible switching. When the ship is in a sailing state, the equipment on the ship is running. At this time, the engine room can provide enough compressed air as an air source, and the compressed air can provide the shutters with power to open and close, thereby achieving the purpose of remote operation of the switch; by opening the air inlet valve 33 and the air outlet valve 35, the compressed air in the engine room can smoothly enter the sealed tank 31 of the first box body 3, so that the compressed air can be guided to be transmitted to the pneumatic switch through the air outlet pipe 34 to achieve the toggle effect, and then the closing of the shutters can be remotely controlled.

[0026] The second box body 4 is arranged on the ship, and a detour pipe 41 is fixedly installed inside the second box body 4 by screws, one end of the detour pipe 41 passes through the first box body 3, the second box body 4 and is fixedly plugged with the sealing tank 31, an input valve 42 is fixedly installed on the detour pipe 41 between the first box body 3 and the second box body 4 by screws, the other end of the detour pipe 41 passes through the second box body 4 and is fixedly connected with the air outlet pipe 34, and an output valve 43 is fixedly installed on the detour pipe 41 outside the second box body 4 by screws; a plurality of electric-controlled valves are arranged at intervals on the detour pipe 41, and the plurality of electric-controlled valves divide the interior of the detour pipe 41 into a plurality of sealed channels, and the opening and closing of the plurality of electric-controlled valves are controlled in sequence at intervals and cooperate with the input valve 42 and the output valve 43 to adjust the air pressure intensity in each sealed channel.

[0027] Among them, by opening the input valve 42, the compressed air inside the sealed tank 31 can enter the detour pipe 41. When the detour pipe 41 is full of compressed air, the input valve 42 is closed again. At this time, the detour pipe 41 is full of compressed air. When the engine room is on fire and the equipment and pipelines on the ship are damaged, the air inlet pipe 32 is most likely to be damaged. At this time, the air inlet pipe 32 in the compressed air will lose the supply of compressed air, and thus it is impossible to normally deliver compressed air to the air outlet pipe 34 to control the closing of the shutters. A large amount of compressed air is retained in the detour pipe 41. At this time, by independently controlling the opening and closing of multiple solenoid valves in sequence, by changing the detour The air pressure intensity in each sealed channel in the tube 41 enables the compressed air in the detour tube 41 to provide compressed air to the outlet pipe 34 in sections, independently and persistently, so that the compressed air can be supplied to the outlet pipe 34 in a directional manner, so as to continue to provide power to the pneumatic switch, thereby controlling the closing of the shutters in an emergency situation, effectively isolating the entry of external air, thereby suppressing the development of the fire, further improving the safety protection effect, and being able to effectively recover the loss of the ship and improve safety. After the fire is under control, the shutters can be restored to the normally open state by manually switching or stopping the supply of compressed air to the inlet pipe 32.

[0028] In order to increase the air pressure strength inside the sealed tank 31, an inflation tube 36 is fixedly connected to the other side of the outer periphery of the first box body 3 by screws, one end of the inflation tube 36 is inserted into the first box body 3 and fixedly plugged with the sealed tank 31, and an inflation valve 37 is fixedly installed on the inflation tube 36 on the outer periphery of the first box body 3 by screws. External compressed air is input into the sealed tank 31 through the inflation valve 37 to increase the air pressure strength in the sealed tank 31, so that when the supply of compressed air in the air inlet pipe 32 is lost, the sealed tank 31 can obtain additional compressed air to complete the delivery of compressed air to the air outlet pipe 34.

[0029] In order to increase the storage capacity of compressed air stored inside the detour pipe 41, a plurality of the detour pipes 41 are provided. The detour pipe 41 is a spiral steel pipe structure. The spiral setting can further increase the storage capacity of compressed air, thereby being able to effectively respond to unexpected emergencies and improving the safety of the ship during navigation.

[0030] In order to continuously and directionally deliver the compressed air in the sealed channel formed in the detour pipe 41 to the air outlet pipe 34, the multiple electrically controlled valves are the first solenoid valve 411, the second solenoid valve 412, the third solenoid valve 413 and the fourth solenoid valve 414 which are spaced apart and fixed on the detour pipe 41 by screws. The first solenoid valve 411, the second solenoid valve 412, the third solenoid valve 413 and the fourth solenoid valve 414 are all one-way solenoid valves. By one-way controlling the delivery direction of the compressed air in the detour pipe 41, the drive of the pneumatic switch can be stably and effectively controlled to close the shutters.

[0031] Specifically, the pneumatic switch includes: a mounting base 2, which is fixedly mounted on a corner end of one side of the shutter by screws, a receiving chamber 21 is provided inside the mounting base 2, one end of the air outlet pipe 34 is fixedly connected to the mounting base 2 by screws and penetrates into the receiving chamber 21, a vent hole 22 is provided in the middle of one side of the outer periphery of the mounting base 2, one end of the vent hole 22 penetrates into the receiving chamber 21 and is communicated with the receiving chamber 21; a baffle 23, which is slidably connected in the receiving chamber 21, the thickness of the baffle 23 is not less than the diameter of the vent hole 22, a guide rod 24 is fixedly mounted on the middle of one side of the baffle 23 by screws, a spring 25 is sleeved on the outer periphery of the guide rod 24, two ends of the spring 25 are respectively fixedly connected to the baffle 23 and the receiving chamber 21 by screws, one end of the guide rod 24 passes through the mounting base 2 and is rotatably mounted with a driving block 26, one side of the driving block 26 is engaged with the paddle of the shutter.

[0032] Among them, the air outlet pipe 34 transports compressed air to the accommodating chamber 21, and the compressed air pushes the baffle 23 to move in the accommodating chamber 21, so that the driving block 26 can be driven by the guide rod 24 to move the paddle of the shutter to close the shutter. During the compressed air transportation process, when the baffle 23 moves away from the air leakage hole 22, the excess compressed air is discharged outward through the air leakage hole 22.

[0033] The manual switch includes: a fixing base 1, which is fixedly installed on the other corner end of one side of the blind by screws, a screw rod 11 is threadedly inserted in the middle of the fixing base 1, one end of the screw rod 11 passes through the fixing base 1 and is rotatably connected to a push block 12, one side of the push block 12 is clamped with a paddle of the blind, and the other end of the screw rod 11 passes through the fixing base 1 and is fixedly installed with a handle 13 by screws; rotating the screw rod 11 by the handle 13 can change the position of the push block 12 on the blind, thereby driving the paddle on the blind to open and close the blind.
