Description

Technical Field

[0001] This invention relates to a physical locking device for electrically controlled lifting doors on ships, belonging to the field of shipbuilding technology. Background Technology

[0002] In the shipbuilding industry, the door structure of boats not only needs to meet basic opening and closing functions, but also needs to adapt to the special operating environment at sea, such as long-term exposure to high humidity, wind and wave impacts, and salt spray corrosion. Simultaneously, it must consider safety, watertightness, and ease of operation. Sealed doors require sufficient strength and watertightness, which results in excessive weight. However, traditional boat doors mostly rely on purely manual operation. Due to the door's weight and complex structure, manual opening and closing is not only labor-intensive but also inefficient and inconvenient for users. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a physical locking device for an electrically controlled lifting door of a boat. It solves the problem that in the prior art, boat doors mostly rely on purely manual operation. Due to the large weight and complex structure of the door, manual opening and closing is not only labor-intensive, but also has low operating efficiency and is inconvenient for people to use.

[0004] The technical problem to be solved by the present invention is achieved by the following technical solution: a physical locking device for an electrically controlled lifting door of a boat, comprising a frame, a support frame fixedly mounted on the frame, a sealing door hinged to the support frame, a drive module for pushing the sealing door to move hinged to the support frame, a locking ring fixedly mounted on the side of the sealing door facing the support frame, a locking tongue mounted on the support frame, and a push structure mounted on the support frame for pushing the locking tongue to engage with the locking ring. The drive module includes an electric push rod and a push rod, the push rod being poweredly connected to the electric push rod, the electric push rod being hinged to the support frame, and the side of the push rod away from the electric push rod being hinged to the sealing door. A control console is fixedly mounted on the frame.

[0005] By adopting the above technical solution, the locking tongue is first moved away from the locking ring on the locking plate by the control console, thus separating the locking tongue from the locking ring. Then, the control console continuously sends control signals to activate the electric push rod. Since the electric push rod and the push rod are hinged to the support frame and the sealing door respectively, the push rod pushes the sealing door to move in a circular motion along the support frame, causing the sealing door to move away from the support frame. Simultaneously, the sealing door moves the locking ring away from the locking tongue, thus separating the locking ring from the locking tongue, and consequently separating the sealing door from the support frame. This device, through the combination of the locking tongue and the electric push rod, achieves electronic control of opening and locking the sealing door. Personnel only need to use the control console to open and lock the sealing door, significantly reducing manpower consumption and effectively solving the problem of low efficiency in manual operation.

[0006] The present invention is further configured such that: the pushing structure includes a locking plate, a locking groove and a control unit; the locking plate is fixedly mounted on the support frame; the locking groove is formed on the locking plate; the locking ring can be inserted into the locking groove; the locking tongue is slidably mounted on the locking plate; and the control unit is mounted on the control console, and the control unit is used to control the insertion or separation of the locking tongue from the locking ring.

[0007] The invention is further configured such that: a mounting hole is provided on the locking plate, and a fixing bolt is provided inside the mounting hole; one end of the fixing bolt can extend into the interior of the support frame and be threadedly connected to the support frame.

[0008] The invention is further configured such that: the control unit includes a start button, a stop button, a first wire rope, and a second wire rope; both the start button and the stop button are located on the control panel; the first wire rope and the second wire rope are respectively connected to the start button and the stop button; and the ends of the first wire rope and the second wire rope away from the control panel are fixedly connected to the locking tongue.

[0009] The present invention is further configured such that: a first micro switch and a second micro switch are fixedly installed on the control panel, and a first receiving rod and a second receiving rod are fixedly installed on the first micro switch and the second micro switch respectively, and the first receiving rod and the second receiving rod can respectively abut against the start button and the stop button.

[0010] By adopting the above technical solution, when the sealed door is closed, firstly, pressing the close button causes the locking tongue on the locking plate to move away from the locking groove under the action of the second steel wire rope, thus separating the locking tongue from the locking groove. At this time, the close button slides towards the second receiving rod under continuous pressing. When the close button abuts against the second receiving rod, a control signal is sent through the second micro switch to start the electric push rod, which pushes the sealing door to move in a circular motion along the support frame, causing the sealing door to move towards the support frame. When the sealing door moves, it simultaneously drives the locking ring to move towards the locking groove, realizing the insertion of the locking ring into the locking plate, thereby achieving the abutment and sealing between the sealing door and the support frame. When the electric push rod reaches the lowest position, it will automatically cut off the power. After the sealing door is completely closed, releasing the close button causes the locking tongue to insert into the locking ring under the action of the second steel wire rope, thus achieving the limit closure.

[0011] The invention is further configured such that a sealing gasket is provided on the side of the support frame facing the sealing door, and the sealing door can abut against the sealing gasket.

[0012] The present invention is further configured such that a handrail is fixedly installed on the control console.

[0013] The present invention is further configured such that: a proximity switch is fixedly installed on the support frame, and an electrical control panel is installed on the control console.

[0014] By adopting the above technical solution, if the sealed door is not completely closed during the closing process, and the proximity switch does not sense the sealed door while the engine is running, the proximity switch will send an alarm reminder to the electrical control panel via the control console. The electrical control panel will display that the sealed door is not closed, urging attention to navigation safety, and reminding the customer service to close the door, thereby improving the safety of the device.

[0015] The beneficial effects of this invention are as follows: First, the locking tongue moves away from the locking ring on the locking plate via the control console, thus separating the locking tongue from the locking ring. Then, the control console continuously sends control signals to activate the electric push rod. Since the electric push rod and the push rod are hinged to the support frame and the sealing door respectively, the push rod pushes the sealing door to move in a circular motion along the support frame, causing the sealing door to move away from the support frame. Simultaneously, the sealing door moves the locking ring away from the locking tongue, achieving separation between the locking ring and the locking tongue, thereby separating the sealing door from the support frame. This device, through the combination of the locking tongue and the electric push rod, achieves electrically controlled operation of opening and locking the sealing door. Personnel only need to use the control console to open and lock the sealing door, significantly reducing manpower consumption and effectively solving the problem of low efficiency in manual operation.

[0023] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0024] like Figures 1 to 3 As shown, a physical locking device for an electrically controlled lifting door on a boat includes a frame 1, a support frame 2 fixedly mounted on the frame 1, a sealing door 3 hinged to the support frame 2, the sealing door 3 being located between the support frames 2, a drive module for moving the sealing door 3 hinged to the support frame 2, a locking ring 4 fixedly mounted on the side of the sealing door 3 facing the support frame 2, a locking tongue 1013 mounted on the support frame 2, and a push structure for pushing the locking tongue 1013 to engage with the locking ring 4. After the locking tongue 1013 engages with the locking ring 4, the sealing door 3 and the support frame 2 are in a sealing abutment state. After separating from the locking ring 4, the sealing door 3 can move away from the support frame 2. The drive module includes an electric push rod 1051 and a push rod 1052. The push rod 1052 is poweredly connected to the electric push rod 1051. The side of the electric push rod 1051 away from the push rod 1052 is hinged to the support frame 2. The side of the push rod 1052 away from the electric push rod 1051 is hinged to the sealing door 3. After the sealing door 3 abuts against the support frame 2, the hinge point between the electric push rod 1051 and the support frame 2 is lower than the hinge point between the push rod 1052 and the sealing door 3, so that the electric push rod 1051 is tilted. A control console 5 is fixedly installed on the frame 1.

[0025] like Figure 4 As shown, the pushing structure includes a locking plate 1011, a locking groove 1012, and a control unit. The locking plate 1011 is fixedly mounted on the support frame 2. There are two locking plates 1011, which are arranged opposite each other on the support frame 2. The locking groove 1012 is vertically opened on the locking plate 1011. The locking ring 4 can be inserted into the locking groove 1012. After the locking ring 4 is inserted into the locking groove 1012, the locking tongue 1013 is aligned with the locking ring 4. The locking tongue 1013 is slidably mounted on the locking plate 1011. The control unit is mounted on the control console 5. The control unit is used to control the insertion or separation of the locking tongue 1013 and the locking ring 4. The locking plate 1011 has four mounting holes 1061, which are located at the four corners of the locking plate 1011 to prevent the locking plate 1011 from deforming due to excessive force on one side. The mounting holes 1061 are equipped with fixing bolts 1062, one end of which can extend into the interior of the support frame 2 and be threadedly connected to the support frame 2.

[0026] like Figure 3As shown, the control unit includes a start button 1021, a stop button 1022, a first steel wire rope 1023, and a second steel wire rope 1024. The start button 1021 and the stop button 1022 are both located on the control console 5 and are electrically connected to the control console 5. The first steel wire rope 1023 and the second steel wire rope 1024 are respectively connected to the start button 1021 and the stop button 1022. The ends of the first steel wire rope 1023 and the second steel wire rope 1024 away from the control console 5 are both fixedly connected to the locking tongue 1013.

[0027] like Figure 5 As shown, a first micro switch 1031 and a second micro switch 1032 are also fixedly installed on the control console 5. A first receiving rod 1033 and a second receiving rod 1034 are fixedly installed on the first micro switch 1031 and the second micro switch 1032, respectively. The first receiving rod 1033 and the second receiving rod 1034 are located below the start button 1021 and the stop button 1022, respectively. The first receiving rod 1033 and the second receiving rod 1034 can respectively abut against the start button 1021 and the stop button 1022. The first micro switch 1031 and the second micro switch 1032 are both electrically connected to the electric push rod 1051 through the control console 5.

[0028] like Figure 1 and Figure 3 As shown, a sealing gasket 1041 is provided on the side of the support frame 2 facing the sealing door 3, and the sealing door 3 can abut against the sealing gasket 1041. A handrail 1071 is fixedly provided on the control panel 5. The handrail 1071 provides stable hand support and helps the operator stabilize their arm posture. Through its own elastic deformation, the sealing gasket 1041 can tightly fill the gap between the sealing door 3 and the support frame 2, thereby improving the sealing performance of the device.

[0029] like Figure 6 As shown, a proximity switch 1081 is fixedly installed on the support frame 2, and an electrical control panel 1080 is installed on the control console 5. The proximity switch 1081 is electrically connected to the electrical control panel 1080 through the control console 5.

[0030] First, press the start button 1021. Under the action of the first wire rope 1023, the start button 1021 moves the locking tongue 1013 away from the locking ring 4 on the locking plate 1011, thus separating the locking tongue 1013 from the locking ring 4. At this time, the start button 1021 slides towards the first receiving rod 1033 under continuous pressure. When the start button 1021 comes into contact with the first receiving rod 1033, a control signal is sent through the first micro switch 1031 to start the electric motor. The push rod 1051, since the electric push rod 1051 and the push rod 1052 are respectively hinged to the support frame 2 and the sealing door 3, the push rod 1052 pushes the sealing door 3 to make a circular motion along the support frame 2, so that the sealing door 3 moves away from the support frame 2. When the sealing door 3 moves, it simultaneously drives the locking ring 4 to move away from the locking plate 1011 in the locking groove 1012, so as to separate the locking ring 4 from the locking plate 1011, thereby realizing the separation of the sealing door 3 from the support frame 2.

[0031] When closing the sealing door 3, first press the closing button 1022. Under the action of the second wire rope 1024, the locking tongue 1013 moves away from the locking groove 1012 on the locking plate 1011, causing the locking tongue 1013 to separate from the locking groove 1012. At this time, the closing button 1022 slides towards the second receiving rod 1034 under continuous pressing. When the closing button 1022 abuts against the second receiving rod 1034, the second micro switch 1032 sends a control signal to start the electric push rod 1051, thereby pushing the rod 1051. Pulling the sealing door 3 along the support frame 2 in a circular motion causes the sealing door 3 to move towards the support frame 2. Simultaneously, the sealing door 3 moves the locking ring 4 towards the locking groove 1012, achieving the insertion of the locking ring 4 into the locking plate 1011, thus achieving a sealing contact between the sealing door 3 and the support frame 2. When the electric push rod 1051 reaches its lowest position, it automatically cuts off power. After the sealing door 3 is completely closed, releasing the close button 1022 causes the locking tongue 1013 to insert into the locking ring 4 under the action of the second steel wire rope 1024, achieving a limited closure. This device, through the combination of the locking tongue 1013 and the electric push rod 1051, achieves the electronic control operation of opening and locking the sealing door 3. Personnel only need to press the start button 1021 or the close button 1022 on the control panel 5 to open and lock the sealing door 3, significantly reducing manpower consumption and effectively solving the problem of low efficiency in manual operation.

[0032] If the sealing door 3 is not completely closed during the closing process, and the proximity switch 1081 does not sense the sealing door 3, while the engine is running, the proximity switch 1081 will send an alarm reminder to the electrical control panel 1080 via the control console 5. The electrical control panel 1080 will display that the sealing door 3 is not closed, reminding passengers to pay attention to navigation safety and reminding the customer service staff to close the door, thus effectively improving the safety of the device.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention.
