Description

Technical Field

[0001] This invention belongs to the field of marine component technology, specifically an integrated hydraulic door. Background Technology

[0002] Ships are a common means of water transportation. Depending on the usage scenario, ships are divided into transport ships, engineering ships, and fishing ships. During the use of ships, in order to ensure the safety of the cabins, it is necessary to isolate the cabins. In the event of water ingress or fire in the cabins, each cabin is isolated to prevent the fire from spreading or large-scale water ingress, reduce property damage, and ensure the safety of the people on board.

[0003] In order to isolate the compartments, existing transport ships use hydraulic doors. Compared with ordinary doors, hydraulic cylinders can provide continuous clamping force, so that the door body is tightly fitted to the door frame and sealing strip, thus ensuring that the compartments are isolated. During use, the hydraulic cylinder pushes the door panel to move horizontally, and proximity sensors are installed on both sides to determine whether the door panel has moved to the correct position. When the door panel moves to the correct position, the hydraulic cylinder stops to ensure that the door panel is stationary. In the event of water ingress or fire, the compartment is isolated, which better protects the safety of the crew on board.

[0004] A patent application with publication number CN119018292B discloses a stable watertight hydraulic door for ships, including a door panel and a door frame hinged to one end of the door panel. A square frame is fixed to one side of the door panel. When the door is closed, the square frame and the door frame are in sealed contact. Multiple door bolts are connected between the door frame and the square frame. The door bolts are set on the square frame and are elastically engaged in grooves opened on the door frame. A door bolt bracket is in contact with the side of the door frame opposite to the square frame. The watertight door has a normal mode, a watertight mode and a fireproof mode. The watertight door in fireproof mode cannot be easily opened, and the crew cannot push the handle L rod without knowing the fire situation.

[0005] In the current use of hydraulic doors, the sealing effect is achieved by applying pressure to the door panel with a hydraulic cylinder and pressing the door panel against the door frame. In order to improve the sealing performance, a sealing strip is installed between the door panel and the door frame. However, the sealing strip will age over time, and the staff cannot know the condition of the sealing strip in time. In case of emergency, the door may fail to seal, which will affect the safety of the staff.

[0006] Therefore, the present invention provides an integrated hydraulic door. Summary of the Invention

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the embodiment of the present invention, an integrated hydraulic door includes a door frame 1. Guide rails 12 are fixed at the top and bottom of one side of the door frame 1. A door panel 11 is slidably connected between the two guide rails 12. Two sets of positioning rollers 111 are rotatably connected to one side of the door panel 11. The positioning rollers 111 are rotatably connected to the outside of the guide rails 12. A pair of proximity sensors 121 are installed below the top guide rail 12. The two proximity sensors 121 are placed on both sides of the door panel 11. A pair of connecting arms 112 are fixed to one side of the door panel 11. Hydraulic cylinders 13 are installed at the top and bottom of the door frame 1 near the door panel 11. The output shaft of the hydraulic cylinder 13 is rotatably connected to the connecting arm 112. A mounting groove 113 is provided on the side of the door panel 11 near the door frame 1. A sealing strip 2 is installed inside the mounting groove 113, and an inflation assembly is provided inside the door panel 11. During use, the door frame 1 needs to be installed at the connection port of the transport ship's cabin, and the installation position must be sealed. A hydraulic device is integrated on one side of the door frame 1, providing real-time oil pressure to the hydraulic cylinder 13. A computer is also installed on one side of the door frame 1, pre-installed with a control system. The control system is connected to the hydraulic device, inflation assembly, proximity sensor 121, control switch, and other electrical devices via wires. During daily use, when personnel need to enter the cabin, the door panel 11 needs to be opened between the door panel 11 and the door frame 1. Pressing the control switch activates the control system, which instructs the hydraulic device to pump oil into the hydraulic cylinder 13. The hydraulic cylinder 13 then pushes the connecting arm 112, which in turn pulls the door panel 11 to move horizontally, thus separating the door panel 11 from one side of the door frame 1. To ensure the door panel 11 remains in a stable horizontal position, guide rails 12 are installed at the top and bottom. The guide rails 12 limit and guide the door panel 11, and positioning rollers 111 are also installed on the guide rails 12. 2. Surface rolling reduces resistance during the translation of door panel 11. During the translation process, the proximity sensors 121 on both sides monitor the position of door panel 11 in real time and transmit the real-time data to the control system. When door panel 11 is translated to the side away from the proximity sensor 121 of door frame 1, the control system determines whether the position of door panel 11 has reached the preset distance based on the data detected by the proximity sensor 121. When the preset data is reached, the control system sends a command to the hydraulic equipment to stop pumping oil, thereby stopping the hydraulic cylinder 13 from pushing the door panel 11 to translate. When it is necessary to close the door panel 11 and door frame 1, press the control switch, and the control system sends a command to the hydraulic equipment to pump oil in the reverse direction to the hydraulic cylinder 13. At this time, the hydraulic cylinder 13 pulls the connecting arm 112 to make the door panel 11 translate in the reverse direction. At this time, the door panel 11 gradually blocks the opening of door frame 1, thereby closing the cabin. When the control system detects that the door panel 11 has moved to the preset distance through the proximity sensor 121 near door frame 1, it sends a command to the hydraulic equipment to stop pumping oil. When the proximity sensor 121 near the door frame 1 detects that the door panel 11 has moved to a preset distance, the control system sends a command to the inflation component to inflate the sealing strip 2. The sealing strip 2 is initially retracted into the mounting groove 113. As the sealing strip 2 is inflated, it gradually expands and fills the gap between the door frame 1 and the door panel 11, thus sealing the gap between the door frame 1 and the door panel 11. When the door panel 11 needs to be moved horizontally, the control system sends a command to the inflation component to extract the gas inside the sealing strip 2, causing the sealing strip 2 to retract into the mounting groove 113. This prevents the sealing strip 2 from wearing out during the horizontal movement of the door panel 11, thus achieving automatic sealing between the door frame 1 and the door panel 11 and preventing wear during daily use.

[0025] like Figures 1 to 7As shown, the inflation assembly includes a first inflation cylinder 23 installed inside the door panel 11. A first spring 233 is fixed to the bottom of the first inflation cylinder 23. A first piston 232 is fixed to the top of the first spring 233. A first push rod 231 is fixed to the top of the first piston 232. An electric telescopic rod 22 is installed on one side inside the door panel 11. A moving plate 221 is fixed to the output shaft end of the electric telescopic rod 22. A slope 224 is provided on one side of the moving plate 221. The slope 224 can be pressed against the top of the first push rod 231. The bottom of the first inflation cylinder 23 is connected to the sealing strip 2 through a connecting assembly. When the sealing strip 2 needs to be inflated, the control system sends a command to activate the electric telescopic rod 22 to push the moving plate 221. The moving plate 221 guides the first push rod 231 downward through the inclined surface 224, which allows the first push rod 231 to push the first piston 232 to move downwards towards the first air cylinder 23. During this process, the gas inside the first air cylinder 23 is input into the sealing strip 2 through the connecting assembly, thereby inflating the sealing strip 2. When the sealing strip 2 needs to be deflated, the control system sends a command to activate the electric telescopic rod 22 to pull the moving plate 221. At this time, the moving plate 221 gradually separates from the first push rod 231. The elastic force of the first spring 233 pushes the first piston 232 to rise automatically. At the same time, the first piston 232 deflates the first air cylinder 23, which allows the first air cylinder 23 to deflate the sealing strip 2 through the connecting assembly, making it easy to control the air pressure inside the sealing strip 2.

[0026] like Figures 1 to 8 As shown, the connecting assembly includes a second connecting plate 25 fixed inside the door panel 11. The bottom end of the second connecting plate 25 is provided with a first air intake channel 251. Two first air delivery channels 252 are provided on both sides inside the second connecting plate 25. The bottom end of the first air cylinder 23 is connected to a first air supply pipe 234. The other end of the first air supply pipe 234 is connected to the first air intake channel 251. The sealing strip 2 is fixed inside with a first air intake pipe 212. One end of the first air intake pipe 212 is connected to a guide pipe 21. The other end of the guide pipe 21 is connected to the first air delivery channel 252. During use, the first air cylinder 23 inputs airflow into the first air inlet channel 251 through the first air supply pipe 234, the first air inlet channel 251 inputs airflow into the air guide pipe 21 through the first air delivery channel 252, and the air guide pipe 21 inputs airflow into the sealing strip 2, thereby realizing automatic inflation of the sealing strip 2.

[0027] like Figures 1 to 8As shown, a set of sealing valve cores 254 are provided on both sides inside the second connecting plate 25. The sealing valve cores 254 are rotatably connected inside the first air supply channel 252. Each set of sealing valve cores 254 is connected by a rotating shaft. A through hole is opened in the middle of the sealing valve core 254. A pressure sensor 253 is installed inside the first air supply channel 252. During use, in order to ensure that the sealing strip 2 is in a stable state, a sealing valve core 254 is installed inside the first air supply channel 252. When the sealing valve core 254 rotates to the point where the through hole connects with the first air supply channel 252, air can be supplied inside the first air supply channel 252. When the sealing valve core 254 rotates to the point where the through hole separates from the first air supply channel 252, the first air supply channel 252 is blocked. At this time, the sealing strip 2 cannot be allowed to enter or exit, making it more stable in use. At the same time, the air pressure sensor 253 can monitor the air pressure of each sealing strip 2 and transmit the air pressure data to the control system.

[0028] like Figures 1 to 8 As shown, a transmission gear is fixed at the top of the rotating shaft of each set of sealing valve cores 254. A second gear 256 is meshed between the two transmission gears. A first gear 255 is fixedly connected above the second gear 256 via a rotating shaft. A first connecting plate 222 is fixed at the top of the moving plate 221. Two racks 223 are provided on one side of the first connecting plate 222. The racks 223 can mesh with the first gear 255. When the electric telescopic rod 22 pushes the moving plate 221 to move, the moving plate 221 drives the rack 223 through the first connecting plate 222. When the first section of the rack 223 meshes with the first gear 255, the first gear 255 drives the second gear 256 to rotate. The second gear 256 drives the transmission gears of the two sets of sealing valve cores 254 to rotate. At this time, the sealing valve core 254 rotates 90°, which allows the inside of the first air delivery channel 252 to communicate with the through hole of the sealing valve core 254, thereby facilitating the delivery of airflow. When the second section of the rack 223 passes the first gear 255, it drives the sealing valve core 254 to continue to rotate 90°. At this time, the through hole of the sealing valve core 254 is disconnected from the first air delivery channel 252, which can realize the automatic switching of the connection state between the sealing valve core 254 and the first air delivery channel 252 in the inflated and non-inflated states of the first air cylinder 23.

[0029] like Figures 1 to 7 As shown, a middle layer 211 is provided in the middle of the sealing strip 2. The middle layer 211 divides the interior of the sealing strip 2 into two cavities. The first air inlet pipe 212 is connected to the cavity near the door frame 1. A second air inlet pipe 213 is fixed on one side of the sealing strip 2. The second air inlet pipe 213 is connected to another cavity inside the sealing strip 2. The second air inlet pipe 213 is connected to the air replenishment component. After prolonged use, the surface of the sealing strip 2 may age and break. When the sealing strip 2 breaks, the corresponding air pressure sensor 253 will detect the change in air pressure of the sealing strip 2 and transmit the air pressure data to the control system, which will then remind the staff. However, at this time, it may not be possible to replace the sealing strip 2 in time. Therefore, at this time, the air supply component will input airflow into the cavity where the second air inlet pipe 213 is located. Under the pressure of the airflow, the intermediate layer 211 will adhere tightly to the side of the sealing strip 2 that is close to the door frame 1. At this time, the intermediate layer 211 can temporarily fill the damaged area on the surface of the sealing strip 2, ensuring that the sealing performance is in good condition during current use.

[0030] like Figures 1 to 7 As shown, the air replenishment assembly includes a second air cylinder 24 fixed to one side of the first air cylinder 23. A second spring 243 is fixed to the bottom of the second air cylinder 24. A second piston 242 is fixed to the top of the second spring 243. A second push rod 241 is fixed to the top of the second piston 242. The top of the second push rod 241 can be in close contact with the inclined surface 224. When the sealing strip 2 has insufficient air pressure, the control system issues a command to make the electric telescopic rod 22 continue to push the moving plate 221. At this time, the moving plate 221 will push the top of the second push rod 241, while the bottom plane of the moving plate 221 will keep the top of the first push rod 231 in the limit position. The second push rod 241 descends to push the second piston 242. The second piston 242 outputs the gas inside the second air cylinder 24. The output gas enters the cavity where the second air inlet pipe 213 is located, thereby achieving a quick temporary seal.

[0031] like Figures 1 to 9 As shown, the bottom end of the second air cylinder 24 is connected to the second air supply pipe 244, and a third connecting plate 26 is fixed on one side of the second connecting plate 25. The bottom end of the third connecting plate 26 is provided with a second air inlet channel 261, and two sets of second air delivery channels 262 are provided on both sides of the second air inlet channel 261. The bottom end of the second air inlet channel 261 is connected to the top end of the second air supply pipe 244, and one side of the second air delivery channel 262 is connected to the second air inlet pipe 213 through the air guide pipe 21. When the second air cylinder 24 outputs gas, the second air cylinder 24 inputs gas into the second air inlet channel 261 through the second air supply pipe 244, the second air inlet channel 261 inputs gas into the second air delivery channel 262, and the second air delivery channel 262 inputs gas into the chamber where the second air inlet pipe 213 is located through the air guide pipe 21, thereby achieving rapid gas replenishment.

[0032] like Figures 1 to 9 As shown, a movable hole 263 is provided in the middle of the first air supply channel 252, and a telescopic column 267 is slidably connected inside the movable hole 263. A through hole is provided inside the telescopic column 267. A telescopic column 267 is installed inside the second air supply channel 262. During normal use, the telescopic column 267 blocks the second air supply channel 262. When it is necessary to replenish the chamber of the second air inlet pipe 213 with air, the telescopic column 267 moves so that its through hole connects with the second air supply channel 262, which can achieve rapid air replenishment.

[0033] like Figures 1 to 9 As shown, a connecting rod 266 is fixed to one end of the telescopic column 267, and a telescopic hole 257 is opened on one side of the first air supply channel 252. A movable ball 264 is slidably connected inside the telescopic hole 257. The movable ball 264 is fixedly connected to the other end of the connecting rod 266. A third spring 265 is fixed to one side of the movable ball 264, and the other end of the third spring 265 is fixedly connected to the inner wall of the telescopic hole 257. When the internal air pressure of the sealing strip 2 is at normal pressure, the movable ball 264 moves into the telescopic hole 257 under pressure. At the same time, the movable ball 264 pulls the telescopic column 267 through the connecting rod 266, so that the through hole of the telescopic column 267 is separated from the second air supply channel 262. When the pressure of the sealing strip 2 is low, the elastic force of the third spring 265 pushes the movable ball 264 to move. At this time, the telescopic column 267 will also move at the same time, so that the through hole is connected to the inside of the second air supply channel 262, thereby enabling precise temporary air replenishment to the inside of the damaged sealing strip 2.
