Description

[0002] In order to avoid collision, marine vessels and engineering structures need to be equipped with various signal devices, which generally have two functions: one is to show the state at the time, and the other is to warn ships sailing nearby, so that nearby ships pay attention. The mast sound and light signal system is a relatively important signal device on the ship, and the industry standard requires detailed requirements for the performance parameters and installation position height of various signal lamps in the mast sound and light signal system. However, during the sailing of the ship, it may be limited by various obstacles (such as bridges) in the route, resulting in the need to lower the height of the signal lamp when passing through, and the signal lamp needs to be designed and installed at the height required by the industry standard when not passing through such obstacles.

[0037] As shown in Figures 1 to 4 The present embodiment first provides a liftable signal lamp device, which comprises a support assembly 1, a signal lamp assembly 2 and a lifting assembly 3. The support assembly 1 comprises a platform 11, two first support rods 12 and two second support rods 13, the two first support rods 12 are respectively arranged on both sides of the platform 11, one end of the first support rod 12 is hinged to the platform 11, and the other end is hinged to the second support rod 13. The support assembly 1 forms a stable five-bar mechanism, has high structural strength and is not easy to deform, can still maintain stability even in harsh marine working environment such as strong wind, avoids breakage of the first support rod 12 and the second support rod 13, and improves the service life of the support assembly 1.

[0038] The signal lamp assembly 2 is arranged between the two second support rods 13, and comprises a signal lamp 21 and a lamp holder rod 22 connected to each other. The specific model of the signal lamp 21 is not limited in the present embodiment. One end of the second support rod 13 away from the first support rod 12 is hinged to one side of the lamp holder rod 22. The signal lamp assembly 2 has a raised state and a retracted state. When the signal lamp assembly 2 is in the raised state, the included angle between the first support rod 12 and the second support rod 13 is obtuse, the top end of the signal lamp 21 is higher than the upper end of the first support rod 12, and the height is relatively high, providing position indication and warning effect. When the signal lamp assembly 2 is in the retracted state, the included angle between the first support rod 12 and the second support rod 13 is acute, the top end of the signal lamp 21 is lower than the upper end of the first support rod 12, and the height is relatively low, facilitating passing through obstacles and avoiding collision between the signal lamp 21 and the obstacles. After passing through the obstacles, the signal lamp assembly 2 returns to the raised state, the signal lamp 21 reaches the height requirement, and continues to provide position indication and warning effect. The specific height of the signal lamp 21 in the raised state and the retracted state is not limited, and can be designed according to industry specification requirements. The support assembly 1 can ensure the installation position accuracy of the signal lamp 21, and is beneficial to improve the navigation safety of the ship.

[0039] The lifting assembly 3 comprises a lowering mechanism 31 and an elastic lifting mechanism 32. The lowering mechanism 31 comprises a lead 311, one end of the lead 311 being connected to the platform 11 and the other end being connected to the signal lamp assembly 2, and the length of the lead 311 is adjustable. When the length of the lead 311 is reduced, the signal lamp assembly 2 can drive the second support rod 13 to rotate relative to the first support rod 12, and at this time, the signal lamp assembly 2 can be changed from the lifted state to the retracted state. The elastic lifting mechanism 32 is connected to the support assembly 1, and the elastic lifting mechanism 32 can drive the second support rod 13 to rotate reversely relative to the first support rod 12, and at this time, the signal lamp assembly 2 can be changed from the retracted state to the lifted state. The lifting assembly 3 has simple structure and simple adjustment mode, and can quickly realize the lifting of the signal lamp assembly 2.

[0040] Optionally, the first support rod 12 comprises a plurality of support longitudinal beams 121 and a plurality of support transverse beams 122, and the plurality of support longitudinal beams 121 and the plurality of support transverse beams 122 are fixedly connected to each other to form a grid structure, which can improve the structural strength of the first support rod 12 and increase the surrounding area of the platform 11 to improve the safety performance. When the operator operates the lifting assembly 3 on the platform 11, the first support rod 12 can be used as a safety fence.

[0041] In an embodiment, the included angle between the first support rod 12 and the platform 11 is obtuse, so that the stability of the support assembly 1 is better. When the signal lamp assembly 2 is changed between the lifted state and the retracted state, the first support rod 12 rotates around the hinge point of the first support rod 12 and the second support rod 13, and at the same time, the other end of the second support rod 13 also rotates around the hinge point of the second support rod 13 and the platform 11, thereby avoiding the support assembly 1 from being stuck.

[0042] In an embodiment, the lowering mechanism 31 further comprises a hand winch 312, and the lead 311 is wound around the hand winch 312, and the hand winch 312 is configured to adjust the length of the lead 311. By operating the hand winch 312, the lead 311 can be pulled, thereby pulling the signal lamp assembly 2 downward to lower the height of the signal lamp 21. The hand winch 312 has a locking function, and when the signal lamp 21 reaches the required height, the hand winch 312 can lock the lead 311 to avoid the lead 311 from being reversed.

[0043] In an embodiment, the lowering mechanism 31 further comprises a screw buckle 313, and the lead 311 is a steel wire rope, which has good structural strength and strong corrosion resistance and is suitable for harsh working environment at sea. One end of the screw buckle 313 is connected to the end of the steel wire rope away from the signal lamp assembly 2, and the other end is connected to the platform 11. The screw buckle 313 is configured to adjust the tightness of the steel wire rope, and the screw buckle 313 and the hand winch 312 interact with each other to adapt the height of the signal lamp 21 to the state of the support assembly 1, thereby avoiding the signal lamp 21 from exerting excessive force on the first support rod 12 and the second support rod 13 to affect the stability of the support assembly 1.

[0044] The structure of the screw buckle 313 and the hand winch 312 is the prior art in the field, and will not be described in detail.

[0045] In an embodiment, the elastic lifting mechanism 32 comprises an elastic hinge 321 hinged between the first support rod 12 and the second support rod 13, which always has a tendency to drive the second support rod 13 to rotate reversely relative to the first support rod 12 to move away from the first support rod 12. When the hand winch 312 is operated to lengthen the lead wire 311, the second support rod 13 rotates reversely around the hinge point with the first support rod 12 under the action of the elastic hinge 321 and returns to the original position.

[0046] In an embodiment, the elastic lifting mechanism 32 further comprises a spring member 322, two ends of which are connected to the two first support rods 12 respectively. In this embodiment, the spring member 322 is a compression spring, which always has a tendency to drive the two first support rods 12 to rotate relative to the platform 11 to move away from each other. In the process of rotating relative to the platform 11 to move away from each other, the two first support rods 12 are driven to rotate, further exerting a force on the first support rods 12 to drive them to rotate reversely and return to the original position, thereby ensuring that the signal lamp 21 can be lifted smoothly.

[0047] In an embodiment, the support assembly 1 further comprises two support cross rods 14, which are arranged on the two sides of the spring member 322 respectively. One end of the support cross rod 14 is fixedly connected to the first support rod 12, and the other end of the support cross rod 14 is connected to the spring member 322. The support cross rod 14 can increase the structural strength of the support assembly 1 and improve the stability of the support assembly 1.

[0048] In an embodiment, the end of the support cross rod 14 away from the first support rod 12 is provided with an end plate 15, and the two end plates 15 are arranged oppositely. The signal lamp assembly 2 further comprises a lamp holder plate 23 connected to the lamp holder rod 22. When the signal lamp assembly 2 is in the retracted state, the lamp holder plate 23 abuts against the upper side of the end plate 15. The end plate 15 can provide a mounting position space for the spring member 322 on the one hand, and can limit the signal lamp assembly 2 on the other hand. When the signal lamp assembly 2 abuts against the upper side of the end plate 15, the height of the signal lamp 21 can be prevented from continuing to decrease.

[0049] In an embodiment, the support assembly 1 further comprises a connecting piece 16, one end of the connecting piece 16 is hinged to one of the two sealing plates 15, and the other end of the connecting piece 16 is detachably connected to the other sealing plate 15. The connecting piece 16 can be an arc-shaped plate, when the signal lamp assembly 2 is in the raised state, the two support cross bars 14 are locked by the connecting piece 16, the spring piece 322 is prevented from acting, the stability of the support assembly 1 is maintained, the signal lamp assembly 2 is always in the raised state, and the position accuracy of the signal lamp 21 is ensured.

[0050] The embodiment of the present application also provides a ship, which comprises the liftable signal lamp device. The ship further comprises a mast 100, which is fixedly connected to the platform 11 of the liftable signal lamp device. The support assembly 1 of the liftable signal lamp device forms a stable five-link mechanism, has high structural strength and is not easy to deform, can maintain stability even in a harsh marine working environment such as strong wind, avoids breakage, improves service life, ensures the position accuracy of the signal lamp 21, and further improves the navigation safety of the ship. The signal lamp assembly 2 has a raised state and a retracted state, when the signal lamp assembly 2 is in the raised state, the top end of the signal lamp 21 is higher than the upper end of the first support bar 12, has a high height, and provides a position indication and warning effect; when the signal lamp assembly 2 is in the retracted state, the top end of the signal lamp 21 is lower than the upper end of the first support bar 12, has a low height, is convenient for passing through an obstacle, avoids collision between the signal lamp 21 and the obstacle, and is beneficial to improve the navigation safety of the ship; the lifting assembly 3 changes the state of the signal lamp assembly 2 through the lowering mechanism 31 and the elastic raising mechanism 32, has a simple structure, a simple adjustment mode, and is easy to quickly realize the lifting of the signal lamp assembly 2.
