Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship safety, in particular to a ship container abandonment device and an operation method thereof. BACKGROUND

[0002] In order to ensure the safety of container cargo and the ship, the container is bound and fixed when the ship is sailing. In order to quickly deal with the out-of-control container, the placement position of the container can be planned according to the danger degree of the cargo in the container, and the container with high risk of fire is loaded on the edge of the deck of the ship. When the container on the edge of the deck of the ship catches fire and the fire is out of control, the container on fire is directly separated from the ship and thrown into the sea, so that the ship fire extinguishing and self-help function is realized with small loss.

[0003] However, the traditional container binding and fixing system (such as twist lock and binding rod) needs manual operation, and it is difficult for personnel to approach and unbind in a high-temperature fire environment, and it is also impossible to push it into the sea in time, so that the fire continues to spread, and therefore there is an urgent need in the industry to develop a scheme capable of quickly dealing with the container on fire on the edge of the deck and eliminating the risk of fire on the ship. SUMMARY

[0004] The present application solves the problem that the container on the edge of the deck of the ship is difficult to unbind and cannot be pushed into the sea in time when the container catches fire and is out of control, and provides a ship container abandonment device and an operation method thereof to solve the technical problem. In the conventional sailing condition, the container is fastened to the ship, and when the container catches fire and is out of control, the container is automatically unbound, the container on fire is dealt with in time, and the ship fire extinguishing and self-help function is realized with small loss.

[0005] To solve the above technical problems, the technical scheme of the present application is as follows:

[0006] A ship container abandonment device is arranged at the lower part of the container and adjacent to the edge of the deck of the ship, comprising a storage tank fixedly connected to the bottom surface of the container to accommodate the bottom part of the container, at least four bases fixedly connected to the deck for supporting the end parts of the bottom part of the storage tank, and a turnover frame for lifting the upper surface of the container to form a plane support, the storage tank is matched with the bottom part of the container, and the outer surface of the bottom part of the storage tank is a plane, the base is further provided with a locking mechanism for controlled locking or unlocking the storage tank, the locking mechanism comprises a bolt structure movably connected with the base, a driving member for driving the bolt structure to move, and the storage tank is provided with a locking hole for inserting the bolt structure.

[0007] The turnover frame is located between the transverse bases, and the longitudinal length of the turnover frame is greater than the longitudinal length of the container, one end of the turnover frame is rotationally connected to the ship deck near the edge of the ship deck, the rotation axis of the turnover frame is a straight line extending in the transverse direction, and the turnover frame is controlled to rotate relative to the ship deck, a plurality of rollers with the same diameter are rotationally connected to the upper surface of the turnover frame, the rotation axis of each roller is parallel to the rotation axis of the turnover frame, and the plurality of rollers are arranged in the longitudinal direction on the upper surface of the turnover frame.

[0008] The turnover frame and the ship deck are provided with a lifting power cylinder for controlling the rotation of the turnover frame, the lifting power cylinder is connected between the ship deck and the turnover frame in a hinged manner, the hinge axes between the lifting power cylinder and the ship deck and the turnover frame are parallel to the rotation axis of the turnover frame, and the two hinge axes between the lifting power cylinder and the ship deck and the turnover frame and the rotation axis of the ship deck and the turnover frame are always non-coplanar during the rotation of the turnover frame.

[0009] Preferably, at least two rows of rollers arranged in the longitudinal direction are arranged on the upper surface of the turnover frame in the transverse direction.

[0010] Preferably, the end close to the edge of the ship deck is defined as the proximal end, the end away from the edge of the ship deck is defined as the distal end, and the rotation axis of the turnover frame is located between the proximal end of the storage tank and the edge of the ship deck.

[0011] Preferably, the proximal end of the upper surface of the turnover frame protrudes from the proximal end of the outer surface of the bottom of the storage tank, or the proximal end of the upper surface of the turnover frame is flush with the proximal end of the outer surface of the bottom of the storage tank.

[0012] Preferably, the movable connection between the pin structure and the base is a sliding connection, the driving member is a pin power cylinder for driving the pin structure to reciprocally slide, the storage tank is provided with a plurality of locking insertion holes, the plurality of locking insertion holes and the plurality of pin structures are one-to-one matched, when the storage tank fixedly connected with the container is located on the base, the pin power cylinder is controlled to drive the pin structure to switch between the state of being inserted into the corresponding locking insertion hole and the state of being separated from the corresponding locking insertion hole.

[0013] An operation method suitable for the container abandonment device for ships described above, comprising the following steps:

[0014] S1-When the container fire is out of control, control the locking mechanism to unlock the storage tank fixedly connected with the container;

[0015] S2-Controlling the turnover frame to rotate upward to lift the container through the storage tank;

[0016] S3 - control the turntable to continue to turn upward until the container slides along the upper surface of the turntable into the water.

[0017] The beneficial technical effects of the technical scheme of the present application are:

[0018] (1) The ship container abandonment device of the present application is arranged at the edge of the deck of the ship, and is suitable for containers whose longitudinal length is perpendicular to the edge of the deck. The abandonment device comprises a locking mechanism, which is controlled to switch between the state of locking the container and the state of unlocking the container by locking and unlocking the storage tank. When the ship is sailing normally, the locking mechanism can be used to lock the container, so that the container remains stable. When the container catches fire and the fire gets out of control, the locking mechanism can be controlled to unlock the container. A turntable is located below the container, and one end of the turntable adjacent to the edge of the deck of the ship is rotationally connected to the deck of the ship. The other end of the turntable is controlled to turn upward, thereby pushing the container on fire to rotate with the turntable.

[0019] The bottom surface of the container is fixedly connected with a storage tank, and the outer surface of the bottom of the storage tank is a plane. Each end of the bottom of the storage tank is fixedly connected with a base fixedly connected with the deck, and the base is at least four and is fixed to the deck, so that the container can be firmly fixed to the deck. A turntable is further arranged below the storage tank. The surface of the turntable facing the storage tank is defined as an upper surface, which constitutes a plane support. A plurality of rollers are rotationally connected to the upper surface of the turntable. The rotational axes of the rollers are parallel to the rotational axis of the turntable, and the arrangement direction of the rollers is perpendicular to the rotational axis of the turntable. When the turntable pushes the container to rotate upward to a certain angle, the turntable supports the storage tank through the rollers. The storage tank and the rollers will slide relative to each other. The container slides down along the upper surface of the turntable together with the storage tank, and finally falls into the water from the turntable. Moreover, since the rollers can reduce the resistance of the container and the storage tank sliding down, the turntable only needs to turn upward by a small angle, so that the container can fall into the water, thereby ensuring that the container on fire at the edge of the deck can be quickly cleaned. In the case of normal sailing, the container is fixed to at least four bases fixedly connected with the deck, and is tightly fixed to the ship, so that the container is not easy to fall off. When the container catches fire and gets out of control, the container on fire can be quickly controlled to fall into the water, without the need for workers to enter the high-temperature environment of the fire, and the risk of the ship catching fire can be eliminated with relatively small loss.

[0020] Furthermore, the rotation axis of the tipping frame is a straight line extending laterally along the container. That is, when the container begins to slide down the top surface of the tipping frame, it is actually sliding along its own length. During the descent of the container, the contact area between the tipping frame and the container decreases at a slower rate, which can ensure that the container slides down smoothly and is less likely to fall out of control. Moreover, the container's descent distance is relatively long, which can ensure that the container has a certain speed when it slides off the tipping frame and is far away from the ship when it enters the water, reducing the problem of the container hitting the ship when it falls into the water.

[0021] (ii) The rollers are arranged in two rows along the longitudinal direction. When the tilting frame rotates upward until the rollers abut against the bottom surface of the storage tank, the top surface of the tilting frame is parallel to the bottom surface of the storage tank. At this time, the storage tank and the rollers below abut against each other at the same time, which can ensure that the tilting frame stably supports the storage tank and the container.

[0022] (iii) The rotation axis of the tipping frame is located between the near end of the storage tank and the edge of the ship's deck. The rotation axis of the container and the storage tank as the tipping frame rotates is also located between the near end of the storage tank and the edge of the ship's deck. The advantage of this setting is that when the tipping frame starts to push the container and the storage tank to rotate upward, the container and the storage tank will directly detach from the base, thereby avoiding the container and the storage tank from colliding with the base and hindering the container abandonment action.

[0023] (iv) The near end of the upper surface of the tilting frame protrudes from the near end of the outer surface of the bottom of the storage tank, or the near end of the upper surface of the tilting frame is adjacent to the outer surface of the bottom of the storage tank, to ensure that the tilting frame can stably support the storage tank and the container to slide toward the edge of the ship's deck, and to avoid the accident of the storage tank and the container falling from the near end of the upper surface of the tilting frame immediately after they detach from the base.

[0032] In order to make the objects, technical solutions and advantages of the present application clearer, a ship container discarding device and its operation method according to the present application are further described in detail below in combination with the drawings and specific embodiments. The advantages and features of the present application will be clearer according to the following description. It should be noted that the drawings are very simplified and all use non-precise proportions, only for the purpose of facilitating and clearly assisting the description of the embodiments of the present application. In order to make the objects, features and advantages of the present application more obvious and easy to understand, please refer to the drawings. It should be understood that the structures, proportions, sizes, etc. shown in the drawings attached to the present specification are only used to cooperate with the content disclosed in the specification, so that those skilled in the art can understand and read, and are not used to limit the conditions for implementing the present application, so they do not have technical substantive significance. Any modification of structure, change of proportion relationship or adjustment of size, without affecting the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0033] The technical solutions of a ship container discarding device and its operation method according to the present application will be described in detail below in combination with the drawings and specific embodiments. Figures 1 to 6 EMBODIMENT

[0034] As Figures 1 to 6 ​As shown, the container abandonment device of the embodiment is arranged adjacent to the edge of the deck of the ship and at the lower part of the container, and comprises a storage groove 8 fixedly connected to the bottom surface of the container 1 to accommodate the bottom of the container 1, at least four bases 7 fixedly connected to the deck and arranged below the storage groove 8 to support the ends of the bottom of the storage groove 8 respectively, and a turnover frame 3 arranged below the storage groove 8 to lift the container 1 and the upper surface of which constitutes a plane support. In the embodiment, the size of the storage groove 8 matches the bottom of the container 1, and the outer surface of the bottom of the storage groove 8 is a plane, and the base 7 is further provided with a locking mechanism for controlled locking or unlocking of the storage groove 8, the locking mechanism comprising a latch structure 5 movably connected to the base 7, a driving member for driving the movement of the latch structure 5, and the storage groove 8 is further provided with a locking hole for insertion of the latch structure. The locking mechanism switches between the state of locking the container 1 and the state of unlocking the container 1 by locking or unlocking the storage groove 8. When the ship is sailing normally, the container 1 can be locked by the locking mechanism to keep the container 1 stable. When the container 1 catches fire and the fire gets out of control, the locking mechanism can be controlled to unlock the container 1.

[0035] Since the container 1 has a uniform specification, a clear transverse and longitudinal direction can be defined according to the container 1, in the embodiment, the transverse direction is the width direction of the container 1, and the longitudinal direction is the length direction of the container 1.

[0036] In the embodiment, four bases 7 are provided, which are respectively arranged at the four corners of the storage groove 8. The turnover frame 3 is a plate-like structure body, which is arranged between the transverse bases 7, i.e., its width is less than the distance between the two transverse bases 7. When the container 1 is installed on the base 7 through the storage groove 8, the turnover frame 3 is located below the container 1 and between the two transverse bases 7, and the longitudinal length of the turnover frame 3 is greater than the longitudinal length of the container 1, and the longitudinal side edges of the bottom of the turnover frame 3 are placed in a non-fixed manner on the supports fixedly connected to the deck. The end of the turnover frame 3 adjacent to the edge of the deck of the ship is rotatably connected to the deck of the ship, and the rotation axis of the turnover frame 3 is a straight line extending in the transverse direction, and the turnover frame 3 is controlled to rotate relative to the deck of the ship.

[0037] In addition, the upper surface of the turnover frame 3 is also rotationally connected with a plurality of rollers 6 of the same diameter, the rotation axis of each roller 6 is parallel to the rotation axis of the turnover frame 3. The upper surface of the turnover frame 3 is located below the outer surface of the bottom of the storage tank 8, the rollers 6 are located between the upper surface of the turnover frame 3 and the outer surface of the bottom of the storage tank 8, the rollers 6 are arranged in the longitudinal direction on the upper surface of the turnover frame 3, and since the rollers 6 are of the same size, the axes of the rollers 6 are parallel to the upper surface of the turnover frame 3 after arrangement. When the turnover frame 3 is rotated upward to abut the rollers 6 against the outer surface of the bottom of the storage tank 8, the upper surface of the turnover frame 3 is parallel to the outer surface of the bottom of the storage tank 8, and the turnover frame 3 abuts the outer surface of the bottom of the storage tank 8 through the plurality of rollers 6 at the same time, thereby providing stable support for the storage tank 8 and the container 1. Since the outer surface of the bottom of the storage tank 8 is a plane, when the turnover frame 3 pushes the container 1 to rotate upward to a certain angle, sliding will occur between the storage tank 8 and the rollers 6, the container 1 slides down along the upper surface of the turnover frame 3 together with the storage tank 8, and finally falls into the water from the turnover frame 3. Moreover, since the rollers 6 can reduce the resistance of the container 1 and the storage tank 8 sliding down, the turnover frame 3 only needs to be rotated upward by a small angle, so that the container 1 can slide into the water, thereby ensuring that the container 1 on fire can be quickly cleaned. In the conventional navigation condition, the container 1 and the ship are tightly fastened and are not easy to fall off, when the container 1 is out of control due to fire, the container 1 on the deck edge can be quickly controlled to fall into the water, the staff does not need to enter the high-temperature environment of the fire, the risk of ship fire can be eliminated with small loss, and the problem of ship damage caused by continuous spread of fire can be avoided.

[0038] The end close to the deck edge of the ship is defined as the proximal end, and the end away from the deck edge of the ship is defined as the distal end, and the rotation axis of the turnover frame 3 is located between the proximal end of the storage tank 8 and the deck edge of the ship. The rotation axis of the turnover frame 3 is located between the proximal end of the storage tank 8 and the deck edge of the ship, so that the rotation axis of the container 1, the storage tank 8 and the turnover frame 3 is also located between the proximal end of the storage tank 8 and the deck edge of the ship. The advantage of this arrangement is that when the turnover frame 3 starts to push the container 1 and the storage tank 8 to rotate upward, the container 1 and the storage tank 8 will directly move upward away from the base 7, thereby avoiding the container 1, the storage tank 8 and the base 7 from colliding and hindering the container 1 from being discarded.

[0039] It should be understood that during the process of lifting the container 1 by rotating the turnover frame 3 upward, it should be ensured that the turnover frame 3 does not contact the base 7, so that the turnover frame 3 can smoothly lift the container 1 without being hindered by the base 7. In the embodiment, the four bases 7 are arranged in two rows in the transverse direction, the turnover frame 3 is located between the two rows of bases 7, and there is a gap between the turnover frame 3 and the two rows of bases 7.

[0040] Specifically, the plurality of rollers 6 includes at least two rows arranged transversely, each row of rollers 6 is uniformly arranged along a direction perpendicular to the rotation axis of the turnover frame 3, and the arrangement of each row of rollers 6 forms a receiving surface parallel to the upper surface. The rollers 6 in this embodiment are two rows, when the turnover frame 3 is rotated upward to the position where the rollers 6 abut against the outer surface of the bottom of the storage tank 8, the outer surface of the bottom of the storage tank 8 simultaneously abuts against the two rows of rollers 6.

[0041] Further, the proximal end of the upper surface of the turnover frame 3 protrudes from the proximal end of the outer surface of the bottom of the storage tank 8, or the proximal end of the upper surface of the turnover frame 3 is flush with the proximal end of the outer surface of the bottom of the storage tank 8, which can ensure that the turnover frame 3 can stably support the storage tank 8 and the container 1 to slide to the edge of the ship deck, avoiding the accident that the storage tank 8 and the container 1 fall immediately from the proximal end of the upper surface of the turnover frame 3 after being separated from the base 7, which will still cause great loss if the container 1 falls on the edge of the ship deck. It should be understood that when implementing the scheme of the present patent, the distance between the proximal end of the turnover frame 3 and the edge of the ship deck should be reasonably designed to ensure that the container 1 can smoothly slide along the turnover frame 3 and fall into the water, and this distance data needs to be obtained through testing, which will not be described here.

[0042] In this embodiment, a lifting cylinder 2 for controlling the rotation of the turnover frame 3 is arranged between the turnover frame 3 and the ship deck, and the lifting cylinder 2 is arranged in the middle of the bottom of the entire turnover frame 3, or arranged in the transverse middle of the bottom of the turnover frame 3 and longitudinally close to the end away from the deck edge. The lifting cylinder 2 is connected between the ship deck and the turnover frame 3 in a hinged manner, the cylinder body of the lifting cylinder 2 is hinged to the ship deck, and the piston rod of the lifting cylinder 2 is hinged to the turnover frame 3, and the hinged axes between the lifting cylinder 2, the ship deck and the turnover frame 3 are all parallel to the rotation axis of the turnover frame 3. And during the rotation of the turnover frame 3, the two hinged axes between the lifting cylinder 2, the ship deck and the turnover frame 3 and the rotation connection point axis between the turnover frame 3 and the ship deck are always not coplanar, so as to avoid the problem that the lifting cylinder 2 is locked. In addition, it should be noted that the position and angle of the lifting cylinder 2 in the drawing are only for illustration, and in actual configuration, the position and angle of the lifting cylinder 2 should be reasonably designed according to the arrangement space and stress relationship to reduce the required thrust for pushing the turnover frame 3 to rotate and improve the working efficiency of the lifting cylinder 2.

[0043] Specifically, the side surface of the storage tank 8 of the embodiment is provided with a plurality of locking insertion holes (not shown in the figure), the locking mechanism comprises a latch structure 5 movably matched with the base 7 and a latch power cylinder 4 for driving the latch structure 5 to move, and each base 7 is provided with a latch structure 5. When the storage tank 8 fixedly connected with the container 1 is located on the base 7, the plurality of latch structures 5 correspond to the plurality of locking insertion holes one by one, and the latch power cylinder 4 drives the latch structure 5 to switch between the state of being inserted into the corresponding locking insertion hole and the state of being separated from the corresponding locking insertion hole, so as to lock or unlock the storage tank 8 and the container 1.

[0044] The storage tank 8 of the embodiment is provided with a locking insertion hole at each corner, and each of the four bases 7 is provided with a latch structure 5. Each latch structure 5 is slidably matched with the base 7 in the transverse direction and correspondingly matched with a locking insertion hole. The latch power cylinder 4 is installed on the deck of the ship and is used to drive the latch structure 5 to reciprocatingly slide, so as to drive the latch structure 5 to switch between the state of being inserted into the corresponding locking insertion hole and the state of being separated from the corresponding locking insertion hole. However, it should be understood that the movement form of the latch structure 5 can also be rotation or other movement forms, as long as the switching between the state of being inserted into the corresponding locking insertion hole and the state of being separated from the corresponding locking insertion hole can be realized.

[0045] In addition, the rotation axis of the turnover frame 3 is parallel to the width direction of the container 1, that is, when the container 1 starts to slide down along the top surface of the turnover frame 3, it is actually sliding in the length direction of the container 1. During the sliding down of the container 1, the contact area between the turnover frame 3 and the container 1 decreases slowly, which can ensure that the container 1 slides down stably and is not easy to fall uncontrollably; and the sliding down stroke of the container 1 is long, which can ensure that the container 1 has a certain speed when it slides off the turnover frame 3, so that the distance between the container 1 and the ship body is far when it falls into the water, thereby reducing the problem of the falling container 1 knocking the ship body.

[0046] In addition, it should be understood that the lifting power cylinder 2 and the latch power cylinder 4 mentioned in the embodiment can be selected from a hydraulic cylinder or an air cylinder.

[0047] The embodiment also provides an operation method suitable for the ship container abandonment device.

[0048] S1-When the container 1 is out of control, the locking mechanism is controlled to unlock the storage tank 8 fixedly connected with the container 1;

[0049] S2- The turnover frame 3 is controlled to rotate upward, and the container 1 is lifted by the storage tank 8.

[0050] S3- The turnover frame 3 is controlled to continue to rotate upward, until the storage tank 8 fixed with the container 1 slides off along the upper surface of the turnover frame 3 together with the container 1 and falls into the water.

[0051] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0052] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
