A ship navigation status monitoring device

Abstract

A device for monitoring the navigation status of a ship comprises a fixed body fixedly mounted on both sides of the bow and stern of a ship's hull, wherein a rotating channel is provided within the fixed body, wherein a rotating sleeve block is rotatably mounted within the rotating channel and abuts against each other in sequence and can slide relative to each other. A high-pressure air channel is provided through the rotating sleeve block and runs through the rotating sleeve block. The high-pressure air channel at the front end is connected to a high-pressure air pump device via a connecting valve. When the ship is in a normal navigation state, the device is mounted on both sides of the exterior of the ship and does not affect the loading and unloading of cargo or navigation. However, when the device detects that the hull or a part of the hull has capsized and become unbalanced due to an imbalance in buoyancy causing the waterline of the hull to rise, the device deploys an airbag to provide additional buoyancy support to the hull at that location, thereby restoring the center of gravity of the hull to balance. Therefore, the device can prevent losses caused by the sinking of the hull in critical moments.

Description

Technical Field

[0001] The present invention relates to the technical field of ship posture monitoring, and in particular to a ship navigation status monitoring device. Background Art

[0002] Water transport has low freight costs, but the conditions beneath the water surface are complex. If a ship capsizes while sailing on the water, the losses caused are large. The main reasons for a ship capsizing include overloading, shifting of the loading center of gravity, hull damage and water ingress, etc. All of these reasons are caused by the imbalance between the buoyancy and gravity of the hull. Therefore, if additional buoyancy support can be provided to the hull or a certain part of the hull when the buoyancy imbalance occurs, the possibility of the hull capsizing can be reduced. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a ship navigation status monitoring device that can monitor the balance between the buoyancy and gravity of the hull, that is, monitor the waterline position of the hull and provide additional buoyancy support to the hull when the waterline rises to a dangerous state, thereby maintaining the balance of the hull.

[0006] A bayonet is provided in the right inner wall of the above-mentioned rotating channel and corresponds to the rotating sleeve block, and an arc-shaped connecting slide connected to the bayonet is provided in the upper inner wall of the rotating channel, and a jumping block with one end extending into the arc-shaped connecting slide and the other end extending into the high-pressure air channel and capable of cooperating with the bayonet is slidably provided in the upper inner wall of the rotating sleeve block, and a pushing assembly is provided between the jumping block and the inner wall of the rotating sleeve block, and an air inlet opening downward is provided in the jumping block, and an air vent is provided at the upper end of the air inlet, and connecting ports that can be connected to the front and rear ends of the vent are respectively provided in the front and rear inner walls of the bayonet.

[0007] A blocking block is slidably provided in the above-mentioned high-pressure gas channel, and guide grooves are respectively provided on the inner walls on the left and right sides of the high-pressure gas channel. Guide sliding blocks that can slide in the guide grooves are respectively provided on the upper and lower sides of the blocking block. The blocking block is used to block the gas flow in the high-pressure gas channel in each section of the rotating sleeve.

[0008] An open port opening to the left is provided in the lower inner wall of the above-mentioned rotating channel, and a ship attitude monitoring device is provided in the open port, which can drive the rotating sleeve to rotate when the ship capsizes. An airbag folding chamber is provided on the right side of the open port and is connected to the lower inner wall. An airbag is folded and placed in the airbag folding chamber. The airbag is fixed to the inner wall of the airbag folding chamber by an anchor point, and the anchor inflation port and the connecting port are connected by a vent hole. A one-way valve is fixed in the vent hole.

[0009] When the above-mentioned ship attitude monitoring device detects that the hull has capsized and caused the liquid level on one side or all of the body to rise, the ship attitude monitoring device drives the rotating sleeve to rotate and when the rotating sleeve rotates ninety degrees and the upper end of the jump block is inserted into the slot, the guide slide groove rotates to be opposite to each other. At this time, the blocking block slides into the high-pressure air channel under the push of the high-pressure airflow, and the guide slider slides in the guide slide groove. When the blocking block reaches the rear end part of the high-pressure air channel of this section of the rotating sleeve, it is blocked by the rotating sleeve on the rear side and stops from sliding, thereby isolating it.

[0010] The front and rear ends of the above-mentioned high-pressure air channel are fixedly provided with guide columns, which pass through the blocking block and are slidably connected to the blocking block. The guide columns are used to limit the blocking block from relative rotation during the sliding process in the high-pressure air channel.

[0013] A locking assembly is provided between the above-mentioned swing arm and the fixed body, and the locking assembly is used to lock the relative position between the fixed body and the swing arm, so that it can be locked when not in use to avoid accidental touch by people.

[0014] An upper fixed anchor is fixedly provided on the upper end face of the fixed body close to the right end face, and a lower dragging body is fixedly provided on the lower end face of the fixed body close to the right end face. The lower dragging body is used to connect the fixed bodies located on the left and right sides of the hull and support the bottom of the hull when the airbag is expanded to generate buoyancy.

[0015] In a preferred solution, the upper end of the jumping block is slidably connected to the inner wall of the arc-shaped connecting slideway.

[0016] In a preferred solution, the airtight block is made of plastic and is used to increase the airtightness of the inner and outer parts of the high-pressure air channel.

[0017] In the preferred solution, two groups of fixed bodies are arranged in the bow and stern of the hull on one side of the hull, and one or more fixed bodies are arranged on the hull on the same side between the two groups of fixed bodies. The fixed bodies are provided with one or more rotating sleeves and one or more air bags. The buoyancy supplement of the hull on one side of the hull can be adjusted more flexibly through the setting of multiple air bags, so as to avoid capsizing of the opposite side due to excessive buoyancy supplement on one side of the hull.

[0018] In the preferred solution, the jumping block is made of a magnet. When the buoyancy block is to be folded back into the open mouth, negative pressure is generated on the front side of the high-pressure air channel to move the blocking block forward, and the jumping block that slides into the bayonet through strong magnet absorption overcomes the elastic force of the traction spring and detaches from the bayonet.

[0020] When the ship is in normal navigation, the device is installed on both sides of the outside of the hull and has no impact on the loading and unloading and navigation of the hull. When the device detects that the hull or a part of the hull is capsized and unbalanced due to the rise of the hull's waterline due to buoyancy imbalance, the device provides additional buoyancy support for the hull at that position by popping out the airbag, so that the center of gravity of the hull is restored to balance. Therefore, the device can avoid losses caused by the sinking of the hull in critical moments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-6 As shown in the figure, a ship navigation status monitoring device includes a fixed body 101 fixedly arranged on both sides of the bow and stern of the hull 102, a rotating channel 121 is provided in the fixed body 101, and a rotating sleeve 117 is rotatably provided in the rotating channel 121, which is abutted in sequence front and back and can slide relatively. A high-pressure air channel 119 is provided in the rotating sleeve 117 so as to pass through the front and back. The high-pressure air channel 119 at the front end is connected to the high-pressure air pump device 105 through the connecting valve 104.

[0031] A bayonet 128 is provided in the right inner wall of the above-mentioned rotating channel 121 and is connected to the rotating sleeve 117. An arc-shaped connecting slide 124 connected to the bayonet 128 is provided in the upper inner wall of the rotating channel 121. A jumping block 142 is slidably provided in the upper inner wall of the rotating sleeve 117, one end of which extends into the arc-shaped connecting slide 124 and the other end extends into the high-pressure air channel 119 and can cooperate with the bayonet 128. A pushing assembly is provided between the jumping block 142 and the inner wall of the rotating sleeve 117. An air inlet 144 opening downward is provided in the jumping block 142, and a vent 143 is provided at the upper end of the air inlet 144. Connecting ports 127 that can be connected to the front and rear ends of the vent 143 are respectively provided in the front and rear inner walls of the bayonet 128.

[0032] A blocking block 134 is slidably provided in the above-mentioned high-pressure gas channel 119, and guide grooves 118 are respectively connected to each other on the left and right inner walls of the high-pressure gas channel 119. Guide sliding blocks 133 that can slide in the guide grooves 118 are respectively provided on the upper and lower sides of the blocking block 134. The blocking block 134 is used to block the gas flow in the high-pressure gas channel 119 in each section of the rotating sleeve 117.

[0033] An open port 107 opening to the left is provided in the lower inner wall of the above-mentioned rotating channel 121, and a ship attitude monitoring device is provided in the open port 107, which can drive the rotating sleeve 117 to rotate when the ship capsizes. An airbag folding chamber 108 is provided on the right side of the open port 107 and is connected to the lower inner wall. An airbag 111 is folded and placed in the airbag folding chamber 108, and the airbag 111 is fixed to the inner wall of the airbag folding chamber 108 by an anchor point 109. The inflation port of the anchor point 109 and the connecting port 127 are connected by a vent hole 131, and a one-way valve is fixed in the vent hole 131.

[0034] When the above-mentioned ship attitude monitoring device detects that the hull 102 has capsized and caused the liquid level on one side or all to rise, the ship attitude monitoring device drives the rotating sleeve 117 to rotate and when the rotating sleeve 117 rotates ninety degrees and the upper end of the jump block 142 is inserted into the bayonet 128, the guide groove 118 rotates to be opposite to each other. At this time, the blocking block 134 slides into the high-pressure air channel 119 under the push of the high-pressure airflow, and the guide slider 133 slides in the guide groove 118. When the blocking block 134 reaches the rear end part of the high-pressure air channel 119 of this section of the rotating sleeve 117, it is blocked by the rotating sleeve 117 on the rear side and stops from sliding, thereby isolating it.

[0035] The front and rear ends of the above-mentioned high-pressure air channel 119 are fixedly provided with guide columns 123, which pass through the blocking block 134 and are slidably connected with the blocking block 134. The guide columns 123 are used to limit the blocking block 134 from relative rotation during the sliding process in the high-pressure air channel 119.

[0036] The above-mentioned pushing assembly includes a pushing groove 145 which is opened on the side of the jumping block 142 and opens outward. An airtight block 146 is fixedly provided on the rotating sleeve 117, which extends into the pushing groove 145 and can slide in the pushing groove 145. A vent is fixedly connected between the lower end face of the airtight block 146 and the lower inner wall of the pushing groove 145.

[0037] The above-mentioned ship attitude monitoring device includes a swing arm 114 fixedly connected to the lower end surface of the rotating sleeve 117. The lower end surface of the swing arm 114 is fixedly connected to a buoyancy block 112, which has buoyancy underwater.

[0038] A locking assembly is provided between the swing arm 114 and the fixed body 101 , and the locking assembly is used to lock the relative position between the fixed body 101 and the swing arm 114 , so that it can be locked when not in use to prevent accidental touching by people.

[0039] An upper fixed anchor 103 is fixedly provided on the upper end face of the fixed body 101 close to the right end face, and a lower dragging body 106 is fixedly provided on the lower end face of the fixed body 101 close to the right end face. The lower dragging body 106 is used to connect the fixed bodies 101 located on the left and right sides of the hull 102, and to support the bottom of the hull 102 when the airbag 111 expands to generate buoyancy.

[0040] The upper end of the jumping block 142 is slidably connected to the inner wall of the arc-shaped connecting slideway 124 .

[0041] The airtight block 146 is made of plastic and is used to increase the airtightness of the inner and outer parts of the high-pressure gas channel 119 .

[0042] When the rotating sleeve 117 rotates and drives the jumping block 142 to rotate ninety degrees clockwise and rotate to the position of the bayonet 128, the jumping block 142 is pulled into the bayonet 128 under the elastic force of the traction spring 151 and the vent 143 is connected to the connecting port 127, so that the high-pressure gas passing through the high-pressure gas channel 119 can be rushed into the airbag 111 to cause it to expand.

[0043] In the preferred solution, two groups of fixed bodies 101 are provided in the bow and stern of the unilateral side hull 102, and one or more fixed bodies 101 are provided on the hull 102 on the same side between the two groups of fixed bodies 101. The fixed body 101 is provided with one or more rotating sleeves 117 and one or more air bags 111. The buoyancy supplement of the unilateral hull 102 can be adjusted more flexibly through the setting of multiple air bags 111, so as to avoid the buoyancy supplement of the unilateral hull being too large and causing the opposite side to capsize.

[0044] In the preferred solution, the jumping block 142 is made of a magnet. When the buoyancy block 112 is to be folded back into the open port 107, negative pressure is generated on the front side of the high-pressure air channel 119 to move the blocking block 134 forward, and the jumping block 142 that slides into the bayonet 128 through strong magnet adsorption overcomes the elastic force of the traction spring 151 and can be detached from the bayonet 128.

[0045] In the initial state, the fixed body 101 is fixedly arranged on the bow and stern on both sides of the hull 102 and above the draft of the hull part by the upper fixed anchor 103 and the lower towing body 106. At this time, the swing arm 114 is in a downward swing state, and the airbag 111 is folded and placed in the airbag folding chamber 108. At the same time, the upper end face of the jump block 142 is against the arc-shaped connecting slide 124, and the blocking block 134 does not slide into the high-pressure air channel 119 in the rotating sleeve block 117 of the rotatable section.

[0046] When the fixed body 101 is immersed below the draft, the buoyancy block 112 floats up as the liquid level rises, thereby driving the swing arm 114 to swing and driving the rotating sleeve 117 to rotate. When the liquid level outside the hull 102 is higher than a certain level and the rotating sleeve 117 is driven by the buoyancy block 112 to rotate ninety degrees, that is, when the jumping block 142 is rotated to the position of the bayonet 128, the jumping block 142 slides into the bayonet 128 under the traction of the elastic tension of the traction spring 151, and the vent 143 is connected to the connecting port 127. At the same time, when the guide slot 118 rotates to the same horizontal position as the guide sliding block 133 as the rotating sleeve 117 rotates, the blocking block 134 Under the pressure difference between the front and rear sides, it moves backward and slides into the high-pressure air channel 119 in the rotating sleeve block 117 after rotating ninety degrees, and the blocking block 134 stays in the high-pressure air channel 119 after rotating ninety degrees under the obstruction of the rotating sleeve block 117 on the rear side of this section of the rotating sleeve block 117. At this time, the blocking block 134 isolates the high-pressure air channel 119 of the front and rear sections. At this time, the high-pressure gas filled by the high-pressure air pump device 105 is introduced into the connecting port 127 through the air inlet 144 and the air vent 143, and is filled into the airbag 111 through the air vent 131, so that the airbag 111 expands and pops out of the airbag folding chamber 108, providing buoyancy for the fixed body 101 at this position.

[0047] The beneficial effects of the present invention are as follows: when the hull is in a normal navigation state, the device is installed on both sides of the outside of the hull, and does not affect the loading and unloading and navigation of the hull. When the device detects that the hull or a part of the hull is overturned and unbalanced due to the rise of the hull's waterline due to buoyancy imbalance, the device provides additional buoyancy support for the hull at that position by popping out the airbag 111, so that the center of gravity of the hull is restored to balance. Therefore, the device can avoid losses caused by the sinking of the hull in critical moments.
